The subsequent full Moon is a near-total lunar eclipse, the Beaver, Frost/Frosty, or Snow Moon; Kartik Purnima, the total Moon of the Festivals of Karthika Deepam, Karthikai Vilakkidu, Thrikarthika, Loi Krathong, Bon Om Touk, and Tazaungdaing; and Ill (or Il) Poya.
The subsequent full Moon will probably be early on Friday morning, November 19, 2021, showing reverse the Sun (in Earth-based longitude) at 3:58 a.m. EST. While this will probably be on Friday for a lot of the Earth, it is going to be Thursday night time from Alaska’s time zone westward to the International Date Line within the Pacific Ocean. The Moon will seem full for about three days round this time, from Wednesday night time by means of Saturday morning.
“This should be a good month for skywatching, with Venus, Jupiter, and Saturn in the evening sky, a potentially visible comet, and one of the best meteor showers of the year!”
— Gordon Johnston
Near-Total Lunar Eclipse
The Moon will probably be so near reverse the Sun on November 19 that it’ll move by means of the southern a part of the shadow of the Earth for a virtually whole lunar eclipse. The partial shadow of the Earth will start falling on the higher left a part of the Moon at 1:02:09 a.m. EST, however the slight dimming of the Moon won’t be noticeable till the total shadow of the Earth begins falling on the higher a part of the Moon at 2:18:41 a.m. The arc of the shadow of the spherical Earth will unfold throughout the Moon till the height of the eclipse at 4:02:53 a.m. when over 97% of the Moon will probably be in full shadow and solely a small sliver of the left aspect of the Moon will shine within the partial shadow of the Earth.
On November 19, 2021 (late night of the 18th in a while zones), the Moon passes into the shadow of the Earth, making a partial lunar eclipse so deep that it could possibly moderately be known as virtually whole. Credit: NASA’s Scientific Visualization Studio
Because the Earth has an environment, the total shadow of the Earth shouldn’t be black. If you had been on the Moon on this shadow and searching again on the Earth, you’d see all the Earth’s sunrises and sunsets falling on you and the floor round you, giving the Moon a reddish-brown colour.
After the height of the eclipse, the total shadow of the Earth will steadily transfer off the Moon to the decrease proper, fully rising from the total shadow at 5:47:04 a.m. After this, the brightening of the Moon because it strikes out of the partial shadow of the Earth will probably be tough to note, particularly since morning twilight will start at 5:54 a.m. The Moon will absolutely exit the partial shadow of the Earth at 7:03:38 a.m., simply earlier than the Moon units on the west-northwestern horizon at 7:06 a.m.
One Moon, Many Names
The Maine Farmers’ Almanac started publishing Native American names for full Moons within the 1930s. Over time these names have change into extensively recognized and used. According to this almanac, as the total Moon in November, that is the Beaver Moon, the Frost or Frosty Moon, or the Snow Moon. For the Beaver Moon, one interpretation is that mid-fall was the time to set beaver traps earlier than the swamps freeze to make sure a provide of heat winter furs. Another interpretation means that the identify Beaver Moon got here from how lively the beavers are on this season as they put together for winter. The Frost, Frosty, or Snow Moon names come from the frosts and early snows that start this time of yr, significantly in northeastern North America.
Throughout Southeast Asia, quite a few associated festivals are celebrated round this full Moon. This is Kartik Purnima (the total Moon of the Hindu lunar month of Kartik) and is well known by Hindus, Jains, and Sikhs (every for various causes). Karthika Deepam, also referred to as Karthikai Vilakkidu or Thrikarthika, is a pageant noticed by Hindus of Tamil Nadu, Sri Lanka, and Kerala when the practically full Moon traces up with the Pleiades constellation (Krittika or Karttikai). Some areas rejoice multi-day festivals that embody this full Moon.
In Thailand and close by international locations, this full Moon is the Loi Krathong pageant, which incorporates adorning baskets and floating them on a river. In Cambodia, this full Moon corresponds with the three-day Bon Om Touk (“Boat Racing Festival”) or the Cambodian Water Festival that includes dragon boat races. In Myanmar, that is the Tazaungdaing Festival, a pageant that predates the introduction of Buddhism and contains the launching of sizzling air balloons (typically flaming or laden with fireworks). In Sri Lanka that is the Ill (or Il) Poya, commemorating the Buddha’s ordination of sixty disciples as the primary Buddhist missionaries.
The Moon’s Connection to Calendars
In most lunisolar calendars the months change with the brand new Moon and full Moons fall close to the center of the lunar months. This full Moon is close to the center of the tenth month of the Chinese calendar, Kislev within the Hebrew calendar, and Rabi? al-Thani (also referred to as Rabi? al-Akhir) within the Islamic calendar. Hanukkah begins on the 25th of Kislev, similar to sunset on Sunday, November 28, 2021.
As normal, the carrying of suitably celebratory celestial apparel is inspired in honor of the total Moon.
Summary of Celestial Events
Here are extra celestial occasions between now and the total Moon after subsequent (with occasions and angles based mostly on the situation of NASA Headquarters in Washington):
This must be a great month for skywatching, with Venus, Jupiter, and Saturn within the night sky, a doubtlessly seen comet, and among the finest meteor showers of the yr!
As autumn ends the every day durations of daylight proceed to shorten. On Friday, November 19, 2021 (the day of the total Moon), morning twilight will start at 5:54 a.m. EST, dawn will probably be at 6:55 a.m., photo voltaic midday will probably be at 11:53:32 a.m. when the Sun will attain its most altitude of 31.52 levels, sundown will probably be at 4:51 p.m., and night twilight will finish at 5:53 p.m.
Using the latitude and longitude of NASA headquarters (and formulation from NOAA), Monday and Tuesday, December 6 and seven are tied for the earliest sunsets of the yr, with sunsets at 4:45:51 p.m. By Saturday, December 18 (the day of the total Moon after subsequent), morning twilight will start at 6:18 a.m., dawn will probably be at 7:22 a.m., photo voltaic midday will probably be at 12:04:53 p.m. when the Sun will attain its most altitude of 27.74 levels, sundown will probably be at 4:48 p.m., and night twilight will finish at 5:52 p.m.

Comet Leonard
Predicted to be the brightest comet of the yr, comet Leonard (C/2021 A1) must be seen with binoculars, and it could change into a naked-eye comet!
Discovered final January by G. J. Leonard on the Mount Lemmon Observatory, this comet will move closest to Earth on December 12, 2021, at 8:54 a.m. EST and attain its closest to the Sun on January 3, 2022, after which it can pace away from the Sun on its method out of our photo voltaic system by no means to return once more.
When and the way vibrant a comet will seem is tough to foretell, as a result of we don’t understand how a lot mud and gasoline the comet will give off (this will fluctuate day-to-day), and this can management how a lot daylight is scattered and mirrored towards us. Depending on the mud and gasoline, the modeled peak brightness is predicted to be round December 13 or 14, 2021, about 1 to 2 days after its closest to the Earth. If the comet is giving off numerous mud, this could make the height brighter attributable to ahead scattering which may shift the height later towards December14.
Keep a watch on the sky and take note of the information, as a result of typically comets can shock us by giving massive outbursts of gasoline and mud as they strategy the Sun, and newer observations and higher fashions can enhance the predictions of how seen this comet may change into.
Around its closest strategy to the Earth, this comet will probably be seen simply earlier than daybreak and simply after nightfall. Note that the occasions and angles I present are based mostly on a selected location. Although the timing relative to sundown and twilight shouldn’t change a lot for latitudes much like that of Washington, the precise clock occasions and time zones could also be totally different in your location. There are quite a lot of on-line astronomy instruments that help you enter your location and get info to information your comet viewing. I like to recommend utilizing one among these to information your comet viewing.
For day-by-day predictions for comet Leonard, see the Detailed Daily Guide under.
Geminid Meteor Shower
One of the most effective and most dependable meteor showers of the yr, the Geminids (004 GEM), is predicted to peak round 2 a.m. on December 14, 2021. The greatest time to look must be after moonset at 2:59 a.m. EST, however earlier than the sky begins to indicate any signal of daybreak (earlier than 6:16 a.m.).
At its peak, beneath perfect situations, this meteor bathe ought to present 140 to 150 seen meteors per hour. This meteor bathe is predicted to be lively from December Four to December 17, with a reasonably broad peak, so with good viewing situations, you might have a great likelihood of seeing some meteors within the mornings earlier than and after the height. Also, the radiant for this meteor bathe is much sufficient north that these of us within the Northern Hemisphere ought to be capable of see just a few meteors which might be vibrant sufficient to be seen regardless of interference from moonlight all through a lot of the night time.
Ideal situations for viewing these meteors can be if the climate is evident with no clouds or excessive hazes, the Moon has set however earlier than any signal of daybreak interferes, you go to a spot removed from any gentle sources or city gentle air pollution, and you’ve got a transparent view of a large expanse of the sky.
Be certain to present your eyes loads of time to adapt to the darkish. The rod cells in your eyes are extra delicate to low gentle ranges however play little position in colour imaginative and prescient. Your color-sensing cone cells are concentrated close to the middle of your view with extra of the rod cells on the sting of your view. Since some meteors are faint, you’ll are likely to see extra meteors from the “corner of your eye” (which is why you want a view of a giant a part of the sky). Your colour imaginative and prescient (cone cells) will adapt to darkness in about 10 minutes, however your extra delicate night time imaginative and prescient rod cells will proceed to enhance for an hour or extra (with a lot of the enchancment within the first 35 to 45 minutes). The extra delicate your eyes are, the extra likelihood you might have of seeing meteors. Even a brief publicity to gentle (from passing automobile headlights, and so on.) will begin the difference over once more (so no turning on a lightweight or your mobile phone to test what time it’s).
This meteor bathe is known as the Geminids as a result of the meteors seem to radiate out from the constellation Gemini. The Geminids are comparatively slow-moving meteors, getting into the Earth’s ambiance at about 35 kilometers per second (78,000 miles per hour). The Geminids look like one among solely two annual meteor showers related to asteroids moderately than comets. The mud that causes the Geminids seems to come back from the asteroid 3200 Phaethon, which has an eccentric 1.Four year-long orbit that takes it out so far as the principle asteroid belt and far nearer to the Sun than Mercury. The downside is that it’s laborious to clarify why there’s a lot mud since we don’t see mud coming off this asteroid now. One risk is that this asteroid might have shot out gasoline and mud previously when it was near the Sun. There are different potential explanations (and due to Bill Cooke at NASA MSFC for offering me with this info just a few years in the past). There is one other asteroid, 2005 UD, that seems to be in a associated orbit. It is feasible that two asteroids collided with each other, producing 2005 UD, 3200 Phaethon, and the huge quantities of particles that trigger the Geminids every year. It can also be potential {that a} bigger physique in the same orbit broke aside attributable to thermal stress or different causes, producing these two asteroids and the Geminids’ stream.
There will probably be a number of different meteor showers throughout this lunar cycle, every anticipated to peak at about 15 seen meteors per hour. Given the issue city skywatchers have in seeing these meteors (and the way lengthy these Moon Missives are already), I’ve opted to not embody descriptions, however if you’re in a great place for meteor watching, you’ll want to look these up!
Evening Sky Highlights
On the night of Friday, November 19, 2021, the day of the total Moon, as night twilight ends (at 5:53 p.m. EST), the brightest planet seen will probably be Venus, showing 14 levels above the southwestern horizon. The subsequent brightest planet will probably be Jupiter, showing 37 levels above the southern horizon. The faintest of the seen planets within the sky will probably be Saturn, showing to the suitable of Jupiter at 31 levels above the south-southwestern horizon. The vibrant star closest to overhead will probably be Deneb, showing 77 levels above the northwestern horizon. Deneb is about 2,600 light-years from Earth and is the 19th brightest star in our night time sky. The vibrant star Aldebaran will simply be rising, showing about Eight levels under the total Moon on the east-northeastern horizon.
As the lunar cycle progresses, Jupiter, Saturn, and the background of stars will seem to shift towards the west every night (though it’s truly the Earth that’s transferring across the Sun towards the east). We are nearing the top of the evenings favorable for Jupiter and Saturn watching. Although each Jupiter and Saturn have been dimming as they transfer away from the Earth, they’ve additionally been shifting towards the west, making them simpler to view within the evenings (and friendlier for yard stargazing, particularly when you’ve got younger ones with earlier bedtimes). The finish of Daylight Savings Time means night twilight ends earlier, nearer to the bedtimes for youthful kids. At the beginning of this lunar cycle, Jupiter will seem about 37 levels above the southern horizon as night twilight ends at 5:53 p.m.
By the night of the total Moon after subsequent, Jupiter will seem about 34 levels above the south-southwestern horizon as night twilight ends (at 5:52 p.m.). With clear skies and a telescope, you must be capable of see Jupiter’s 4 vibrant moons, Ganymede, Callisto, Europa, and Io, noticeably shifting positions in the middle of a night. For Saturn, you must be capable of see Saturn’s rings in addition to Saturn’s largest moon, Titan.
Unlike Jupiter, Saturn, and the background of stars, the intense planet Venus will seem to shift left alongside the southwestern horizon every night till November 14, after which it can start to begin to shift again towards the suitable.
Venus will seem at its highest above the horizon as night twilight ends round November 28, 2021. Venus will seem to brighten because it shifts nearer to the Earth till it reaches its biggest brightness in early December, after which it can lower in brightness because it continues to shift towards the horizon.
The waxing crescent Moon will seem close to Venus on the night of December 6, Saturn on December 7, and Jupiter on December 8.
December 15 would be the first night that the planet Mercury will seem above the west-southwestern horizon 30 minutes after sundown (an approximation of when it could begin being seen within the glow of nightfall).
Comet Leonard will begin showing above the horizon about 30 minutes after sundown on the night of December 9. It will change into brighter and better within the sky because it approaches its closest to the Earth on December 12 and can attain its predicted most brightness one or two evenings after that. For extra particulars see the outline above or the Daily Guide under.
By the night of Saturday, December 18, 2021 (the day of the total Moon after subsequent), as night twilight ends (at 5:52 p.m. EST), the brightest planet seen will probably be Venus, showing 11 levels above the southwestern horizon. The subsequent brightest planet will probably be Jupiter, showing 34 levels above the south-southwestern horizon. The faintest of the seen planets within the sky will probably be Saturn, showing to the suitable of Jupiter at 21 levels above the southwestern horizon. The planet Mercury can have already set by the point night twilight ends, however it could be seen when you’ve got a really clear view of the southwestern horizon from about 30 minutes after sundown (5:18 p.m.) till Mercury units 9 minutes later. No significantly vibrant star will seem overhead, with Deneb nonetheless the closest at 58 levels above the west-northwestern horizon.
Morning Sky Highlights
On the morning of November 19, 2021 (the day of the total Moon), as morning twilight begins (at 6:25 a.m. EST), the one seen planet within the sky will probably be Mars, showing only a diploma above the east-southeastern horizon. The vibrant stars of the native arm of our dwelling galaxy will seem unfold throughout the southwestern horizon. The vibrant star showing closest to instantly overhead will probably be Pollux at 64 levels above the west-southwestern horizon, with Regulus an in depth second at 62 levels above the south-southeastern horizon. Pollux is the brighter of the twins within the constellation Gemini and is about 34 light-years from us. Regulus seems to us as one star (the 21st brightest star in our sky), however it’s truly two pairs of stars orbiting one another for a complete of Four stars. Regulus is 79 light-years from us.
As the lunar cycle progresses Mars and the background of stars will seem to shift towards the west every morning. The waning Moon will seem close to Pollux on November 24, Regulus on November 27, Spica on December 1, and Mars on December 2, 2021.
Comet Leonard will probably be seen within the morning sky, passing 5 levels to the left of Arcturus on December 6. This comet ought to proceed to brighten because it strikes towards the horizon every morning. The morning of December 12 would be the final morning comet Leonard will seem above the horizon as night twilight ends. This may even be close to its closest to the Earth and practically at its predicted most brightness. The subsequent morning, December 13, this comet will rise about 12 minutes after morning twilight begins, and this would be the final morning the comet may be seen within the morning sky. For extra particulars see the outline above or the Daily Guide under.
As talked about above, the Geminid meteor bathe is predicted to peak the morning of December 14. The greatest time to look must be after moonset (at 2:59 a.m. EST) however earlier than the sky begins to indicate any signal of daybreak (earlier than 6:16 a.m.). Under perfect situations, this meteor bathe can peak at 140 to 150 seen meteors per hour.
By the morning of December 18, 2021 (the day of the total Moon after subsequent), as morning twilight begins (at 6:25 a.m. EST), the one seen planet within the sky will probably be Mars, showing 7 levels above the southeastern horizon. The vibrant stars of the native arm of our dwelling galaxy can have already set. No significantly vibrant star will seem near overhead, with the closest being Arcturus at barely greater than 54 levels above the east-southeastern horizon. An in depth second will probably be Regulus at barely lower than 54 levels above the southwestern horizon. Arcturus is the 4th brightest star in our night time sky and is 36.7 light-years from us. While it has about the identical mass as our Sun, it’s about 2.6 billion years older and has used up its core hydrogen, turning into a crimson large about 25 occasions the dimensions and 170 occasions the brightness of our Sun.
Detailed Daily Guide
Here is a extra detailed, day-by-day itemizing of celestial occasions between now and the total Moon after subsequent (with occasions and angles based mostly on the situation of NASA Headquarters in Washington):
NOVEMBER
November 13
Beginning Saturday morning, November 13, 2021, the planet Mars will start showing above the east-southeastern horizon as morning twilight begins.
November 18
Thursday morning, November 18, 2021, would be the final morning that Mercury will probably be above the horizon 30 minutes earlier than dawn, and an approximation of when Mercury will cease being seen within the glow of daybreak for this apparition.
November 19: Full Moon and Partial Lunar Eclipse
As talked about above, the following full Moon will probably be on Friday morning, November 19, 2021, at 3:58 a.m. EST. The Moon will seem full for about three days round this time, from Wednesday night time by means of Saturday morning. This will probably be a partial eclipse of the Moon. The slight dimming of the Moon will in all probability not be noticeable till the total shadow of the Earth begins falling on the higher a part of the Moon at 2:18:41 a.m.. The peak of the eclipse will probably be at 4:02:53 a.m., with over 97% of the Moon within the full shadow, turning a reddish-brown, and solely a small sliver of the left aspect of the Moon will shine within the partial shadow of the Earth. The full shadow of the Earth will transfer off the Moon to the decrease proper and the Moon will end rising from the total shadow at 5:47:04 a.m. Morning twilight will start at 5:54 a.m. and the Moon will set on the west-northwestern horizon at 7:06 a.m.
November 20
Saturday night, November 20, 2021, at 9:13 p.m. EST, the Moon will probably be at apogee, its farthest from the Earth for this orbit.
November 23-24
Tuesday night time into Wednesday morning, November 23 to 24, 2021, the intense star Pollux will seem close to the waning gibbous Moon. Pollux will probably be to the higher left of the Moon because the Moon rises above the east-northeastern horizon (at 8:05 p.m. EST), Pollux will probably be to the higher proper of the Moon because it reaches its highest within the sky for the night time Wednesday morning at 3:51 a.m., and Pollux will probably be to the suitable of the Moon as morning twilight begins at 5:59 a.m.
November 26-27
Friday night time into Saturday morning, November 26 to 27, 2021, the intense star Regulus will seem close to the waning half-full Moon. Regulus will rise to the suitable of the Moon because the Moon rises above the east-northeastern horizon at 11:10 p.m. EST, and it is going to be farther to the decrease proper of the Moon Saturday morning as morning twilight begins at 6:02 a.m.
Saturday morning, the waning Moon will seem half-full because it reaches its final quarter at 7:28 a.m. EST.
November 28
On Sunday, November 28, 2021, the intense planet Venus will seem at its highest above the horizon as night twilight ends, 15 levels above the southwestern horizon. Because the angle of the road between the Sun and Venus and the road of the horizon modifications with the seasons, the date when Venus seems highest above the horizon as night twilight ends, shouldn’t be the identical as when Venus and the Sun seem farthest aside as seen from the Earth, which occurred on October 29.
On Sunday night time, the planet Mercury will probably be passing on the far aspect of the Sun as seen from the Earth, known as superior conjunction. Because Mercury orbits within the orbit of Earth, it is going to be shifting from the morning sky to the night sky and can start rising from the glow of the nightfall on the western horizon in mid-December 2021 (relying upon viewing situations).
DECEMBER
December 1
On the morning of December 1, 2021, the intense star Spica will seem about Eight levels to the higher proper of the waning crescent Moon. The Moon will rise within the east at 3:42 a.m. EST about 2 hours, 22 minutes earlier than morning twilight begins at 6:05 a.m.
December 2
On Thursday morning, December 2, 2021, the planet Mars will seem about Eight levels to the decrease left of the skinny waning crescent Moon. Mars will rise above the east-southeastern horizon at 5:40 a.m. EST, and the Moon will seem 11 levels above the horizon as morning twilight begins at 6:06 a.m. By the following night, the Moon can have shifted to seem under Mars, however it can rise after morning twilight begins, making it more durable to see.
December 4
Saturday morning, December 4, 2021, at 2:43 a.m. EST, would be the new Moon, when the Moon passes between the Earth and the Sun and won’t be seen from the Earth. For Antarctica, the southern ideas of Africa and Australia, and the oceans close to these areas, this will probably be a partial eclipse of the Sun. For a slender crescent from the South Atlantic off of Argentina throughout a part of Antarctica to the South Pacific off of Chile, this will probably be a complete eclipse of the Sun. My plans to be on a ship within the South Atlantic to view this eclipse have been canceled because of the COVID-19 pandemic.
The day of or the day after the New Moon marks the beginning of the brand new month for many lunisolar calendars. The eleventh month of the Chinese calendar begins on December 4, 2021 (at midnight in China’s time zone, which is 13 hours forward of EST). Sundown on Saturday, December 4, will mark the beginning of Tevet within the Hebrew calendar, which may even be the beginning of the seventh day of Hanukkah. In the Islamic calendar, the months historically begin with the primary sighting of the waxing crescent Moon. Many Muslim communities now observe the Umm al-Qura Calendar of Saudi Arabia, which makes use of astronomical calculations to start out months in a extra predictable method. Using this calendar, sunset on Saturday night, December 4, will mark the start of Jumada al-Awwal, also referred to as Jumada al-Ula.
On Saturday morning, December 4, 2021, at 5:05 a.m. EST, the Moon will probably be at perigee, its closest to the Earth for this orbit.
December 6
On Monday morning, December 6, 2021, as morning twilight begins at 6:10 a.m. EST, comet Leonard will seem about 44 levels above the jap horizon and about 5 levels to the left of the intense star Arcturus, which ought to provide you with a great information star for locating this comet with binoculars. Each morning after this the comet ought to brighten because it shifts considerably towards the horizon.
Using the latitude and longitude of NASA headquarters, Monday and Tuesday, December 6 and seven, 2021, are tied for the earliest sunsets of the yr, with sunsets at 4:45:51 p.m. EST.
On Monday night, December 6, 2021, the intense planet Venus, close to its most brightness, will seem about 4.5 levels above the skinny waxing crescent Moon. The Moon will seem about 11 levels above the southwestern horizon as night twilight ends (at 5:49 p.m. EST) and the Moon will set first 1 hour, 25 minutes later (at 7:14 p.m.).
December 7
On or about Tuesday, December 7, 2021, the planet Venus is predicted to succeed in its biggest brightness for this apparition. Venus has been brightening because it strikes nearer to Earth, despite the fact that it is usually presenting extra of a crescent. If the ambiance of Venus mirrored gentle evenly in all instructions (known as Lambertian reflectance), its biggest brightness can be on December 3. Astronomers use the time period “greatest brilliance” to differentiate this idealized reflection from the precise biggest brightness. Forward scattering by the ambiance of Venus causes the best brightness to happen at a better angle between the Sun, Venus, and the Earth (known as part angle). The predicted peak brightness relies upon upon fashions of forward-scattering by the ambiance of Venus, and the predictions I’ve discovered point out this could happen on December 7. After this most brightness, Venus will lower in brightness rapidly because it shifts towards the horizon and presents extra of its darkish aspect on its technique to move between the Earth and the Sun.
On Tuesday night, December 7, 2021, the planet Saturn will seem about 6 levels above the skinny waxing crescent Moon. The Moon will seem about 20 levels above the south-southwestern horizon as night twilight ends (at 5:49 p.m. EST) and the Moon will set first 2 hours, 38 minutes later (at 8:27 p.m.).
December 8
On Wednesday night, December 8, 2021, the intense planet Jupiter will seem above the waxing crescent Moon. The Moon will seem about 28 levels above the south-southwestern horizon as night twilight ends (at 5:49 p.m. EST) with Jupiter about Eight levels to the higher proper. The Moon will set first on the west-southwestern horizon Three hours, 51 minutes later (at 9:40 p.m.), with Jupiter about 6 levels to the higher proper.
December 9
On Thursday night, December 9, 2021, comet Leonard will begin showing above the west-northwestern horizon about 30 minutes after sundown (5:16 p.m. EST). It will shift barely increased and considerably towards the left every night after that.
December 10
On Friday night, December 10, 2021, the Moon will seem half-full because it reaches its first quarter at 8:36 p.m. EST.
December 12
On Sunday morning, December 12, 2021, as morning twilight begins at 6:14 a.m. EST, comet Leonard will seem 4.5 levels above the jap horizon. This must be a great time to search for this comet, as later within the day at 8:54 a.m. EST it is going to be at its closest to the Earth.
On Sunday night, December 12, 2021, about 30 minutes after sundown at 5:16 p.m. EST, Comet Leonard will seem 6.5 levels above the western horizon. This must be a great time to search for the comet, as it is going to be setting simply as night twilight ends (at 5:50 p.m.).
December 13
The subsequent morning, Monday, December 13, 2021, comet Leonard will rise at 6:37 a.m. EST about 12 minutes after morning twilight begins and can seem lower than 2 levels above the jap horizon 30 minutes earlier than dawn at 6:48 a.m. This would be the final morning the comet will probably be seen within the morning sky till March of 2022 when it can solely be seen by means of a big telescope.
On Monday night, December 13, 2021, comet Leonard will seem Eight levels above the west-southwestern horizon about 30 minutes after sundown at 5:17 p.m. EST, and it’ll nonetheless be about 2 levels above the horizon as night twilight ends at 5:50 p.m. This once more must be a great time to search for this comet.
December 14
As talked about above, the Geminid meteor bathe is predicted to peak early on the morning of Tuesday, December 14, 2021. The greatest time to look must be after moonset after 2:59 a.m. EST, however earlier than the sky begins to indicate any signal of daybreak earlier than 6:16 a.m. Under perfect situations, this meteor bathe can peak at 140 to 150 seen meteors per hour.
On the night of Tuesday, December 14, 2021, comet Leonard will seem 9 levels above the west-southwestern horizon about 30 minutes after sundown at 5:17 p.m. EST, and it is going to be about 3.5 levels above the horizon as night twilight ends at 5:50 p.m. If this comet is giving off numerous mud that causes ahead scattering (like the intense glow across the fringe of a cloud that’s blocking the Sun), this may be close to when the comet is at its most brightness.
December 15
On Wednesday night, December 15, 2021, comet Leonard will seem 10 levels above the southwestern horizon about 30 minutes after sundown at 5:17 p.m. EST, and it is going to be about 4.5 levels above the west-southwestern horizon as night twilight ends at 5:50 p.m. Over the following few evenings, the comet will seem to shift to the left and barely increased alongside the horizon every night time, however it’s anticipated to start to seem dimmer because it strikes away from Earth.
