EarthSky Minute, moon phases December 2023

December 21 and 22 evenings: Moon near Jupiter

On the evenings of December 21 and 22, 2023, the waxing gibbous moon will glow near the bright planet Jupiter. The moon and Jupiter will set several hours after midnight.

December solstice: December 21-22

The December solstice is at 3:27 UTC on December 22, 2023 (9:27 p.m. December 21 CST). Winter arrives in the Northern Hemisphere and summer arrives in the Southern Hemisphere.

December 22: Mercury will pass between Earth and the sun

Mercury will reach the point in its orbit known as inferior conjunction – when it passes between Earth and the sun – at 19 UTC on December 22.

December 22-23 mornings: Ursid meteor shower

The predicted peak of the Ursid meteor shower is on the early mornings of December 22 and 23, 2023. The best time to watch is before dawn and after the waxing gibbous moon has slipped below the horizon.

December 23 and 24 evenings: Moon near the Pleiades

The bright waxing gibbous moon will pass the Pleiades star cluster on the evenings of December 23 and 24, 2023. The Pleiades is also known as the Seven Sisters or Messier 45 and appears as a glittering, bluish cluster of stars in the constellation Taurus the Bull. The moon and Pleiades will cross the sky together until about an hour before sunrise.

December 25 all night: Moon near Capella, Aldebaran and Betelgeuse

December 25, 2023, the bright waxing gibbous moon will lie near a trio of bright stars. It’ll be near the fiery orange star Aldebaran of Taurus the Bull and Orion’s mighty red supergiant star Betelgeuse. The bright golden star is Capella of the constellation Auriga the Charioteer. If you catch Capella low on the horizon, it may be flashing like a small disco ball. You can follow them all night until sunrise.

December 26-27, all night: Full Moon

The instant of full moon will fall at 0:33 UTC on December 27, 2023 (6:33 p.m. CST December 26).

Our charts are mostly set for the northern half of Earth. To see a precise view – and time – from your location, try Stellarium Online.

December 26 and 27 evenings: Moon near Castor and Pollux

On the evening of December 26, 2023, the full moon will pass Castor and Pollux, the twin stars of Gemini. Then on the evening of December 27, the waning gibbous moon will be closer to the Twin Stars of Gemini. They’ll rise a few hours after sunset and be visible traveling across the sky all night.

December 29 morning: Moon near the Beehive

For the second time this month, the moon will slide by the famous – but faint – Beehive star cluster. This time it will be a waning gibbous moon on the morning of December 29, 2023. You will need binoculars to spot the dozens of stars in the busy Beehive star cluster. Also nearby will be the twin stars, Castor and Pollux, in the constellation Gemini. They’ll rise late the night before and be high in the morning sky.

December 30 and 31 mornings: Moon near the Sickle

On the mornings of December 30 and 31, 2023, the waning gibbous moon will float near Regulus, marking the bottom of the backward question mark asterism called the Sickle. Regulus is the brightest star in Leo the Lion. And the moon will lie close to Regulus on the final morning of 2023. They’ll rise late in the evening the night before and be high in the morning sky.

Our charts are mostly set for the northern half of Earth. To see a precise view – and time – from your location, try Stellarium Online.

Planets in December 2023

December mornings: Venus

The blazing light of Venus will continue to dominate the morning sky through the end of the year. However, it will be sinking lower each morning after it reached its greatest elongation from the sun in October. Luckily, it will rise early enough to see it in dark skies. Venus will begin the month at -4.2 magnitude and will dim slightly as it recedes from Earth, ending the month at -4.1 magnitude. A lovely waning crescent moon will join Venus on the morning of December 9, 2023, when they appear about 4 degrees apart. Also, Venus will appear close to the star Spica at the beginning of the month, and then they drift apart more each morning. Venus begins the month in the constellation Virgo the Maiden and will move into Libra the Scales by mid-month. Then by month’s end, it will be in the constellation Scorpius the Scorpion.

December most of the night: Jupiter

Bright Jupiter will draw your attention most of the night. It will be very obvious in the east at sunset and will be visible until a few hours before dawn. It will shine near the pretty Pleiades star cluster in the constellation Taurus the Bull. Jupiter reached its closest point to the Earth in early November. And it reached opposition overnight on November 2-3, 2023, when we flew between it and the sun. So, as Jupiter recedes from Earth, it’ll fade a bit in our sky. It will lie in the dim constellation Aries the Ram. It will shine at -2.7 magnitude by month’s end. The waxing gibbous moon will float by Jupiter on December 22, 2023.

December evenings: Saturn

Golden Saturn will shine in the southwest after sunset during December. It will be in the dim constellation Aquarius the Water Bearer. Our solar system’s beautiful ringed planet will be fading a bit this month as it recedes from Earth and will shine at +0.9 magnitude for most of the month. Saturn will be a little brighter than the nearby lonely star, Fomalhaut, which shines around 1st magnitude. The waxing gibbous moon will visit Saturn on the evenings of December 17, 2023. Saturn will set by mid-evening your local time this month.

December evenings: Mercury

Mercury will be emerging low in the morning sky the last few days of the year on its way to its first greatest morning elongation of 2024.

Where’s Mars?

It’s too close to the sun in the morning sky to be visible for the rest of 2023. It’ll be back next year.

Now that winter is almost here, we can look forward to the last meteor shower of the year. Next up are the December Ursids.and January Quadrantids

Meteor shower around the December solstice … the Ursids

Predicted peak: is predicted** for December 23, 2023, at 4 UTC.
When to watch: Watch for Ursid meteors in the early morning hours of December 22 and 23.
Duration of shower: Ursids range from December 13 to 24, so you might see some intermingling with the Geminids’ peak.
Radiant: Circumpolar at northerly latitudes.
Nearest moon phase: A 1st quarter moon occurs at 18:39 UTC on December 19. So the waxing gibbous moon – at 86% illumination – may interfere with the Ursids in 2023 until the moon sets about three hours before sunrise.
Expected meteors at peak, under ideal conditions: Under a dark sky with no moon, the Ursids offer perhaps five to 10 meteors per hour.
Note: This low-key meteor shower – which always peaks around the solstice – is somewhat overlooked due to the holiday season. Its hourly rate is lower than that of the popular Geminid shower, which peaks over a week before.

Read more: Ursid meteors peak around December solstice

Early January 2024 meteors … the Quadrantids

When to watch: The best night for the 2024 Quadrantids is January 3-4 (The predicted peak** is 12:53 UTC on January 4). A bright last quarter moon will rise around midnight and shine the rest of the night. Try late night January 3 to dawn January 4, in moonlight.
Nearest moon phase: Last quarter moon will come late on January 3, 2024 (CST).
Radiant: Rises in the north-northeast after midnight and is highest up before dawn. The radiant point for the Quadrantids is in a now-obsolete constellation, Quadrans Muralis the Mural Quadrant. Nowadays, we see the radiant near the famous Big Dipper asterism. Because the Quadrantid radiant is far to the north on the sky’s dome, this is mostly a far-northern shower, not as good for the Southern Hemisphere.
Expected meteors at peak, under ideal conditions: Under a dark sky with no moon, when the radiant is high in the sky, the Quadrantids can (briefly) produce over 100 meteors per hour.
Duration of shower: The Quadrantid meteor shower runs from mid-November through mid-January each year, according to this 2017 article in the journal Icarus. You might see a Quadrantid streak by any time during that interval. But most activity is centered on the peak.
Note: The Quadrantid shower is one of four major meteor showers each year with a sharp peak (the other three are the Lyrids, Leonids, and Ursids).

Read more: All you need to know about Quadrantid meteors

April 2024 meteors … the Lyrids

When to watch in 2024: Late evening April 21 until dawn April 22 will be best. The predicted** peak is 9:23 UTC on April 22. The peak of the Lyrids is narrow (no weeks-long stretches of meteor-watching, as with some showers). In 2024, the full moon falls at 23:49 UTC on April 23. So meteor watching will be impacted by a bright waxing gibbous moon.
Radiant: Rises before midnight, highest in the sky at dawn.
Nearest moon phase: Full moon falls at 23:49 UTC on April 23. So a bright waxing gibbous moon will be in the sky during the peak morning for the 2023’s Lyrid meteor shower.
Duration of shower: April 15 to April 29.
Expected meteors at peak, under ideal conditions: In a dark sky with no moon, you might see 10 to 15 Lyrids per hour. The Lyrids are known for uncommon surges that can sometimes bring rates of up to 100 per hour! Read more about Lyrid outbursts.
Note for Southern Hemisphere: This shower’s radiant point is far to the north on the sky’s dome. So the Southern Hemisphere will see fewer Lyrid meteors. Still, you might see some!

Read more: All you need to know about Lyrid meteors

May 2024 meteors … the Eta Aquariids

When to watch: New moon will fall a few days after the peak of the 2024 Eta Aquariid shower. So, mornings around the peak will be dark and moonless. The best mornings to watch are May 5 and 6, 2024, in the hours before dawn. Why before dawn? See “Radiant” below.The American Meteor Society is listing 8:43 UTC on May 5 as the shower’s predicted** peak time. But times vary between different experts. And the peak of this shower stretches out over several days. So you can expect elevated numbers of meteors a few days before and after the peak time.
Nearest moon phase: New moon will fall at 03:22 UTC on May 8. So moonlight will not obscure the 2024 Eta Aquariids.
Radiant: Will rise in the wee hours, climbing toward its highest point at dawn. That’s why before dawn will be the best time to watch this shower.
Duration of shower: April 15 to May 27.
Expected meteors at peak, under ideal conditions: In the southern half of the U.S., you might see 10 to 20 meteors per hour under a dark sky, with no moon, when the radiant is high in the sky. Farther south – at latitudes in the Southern Hemisphere – you might see two to three times that number.
Note: The Eta Aquariids’ radiant will be on the ecliptic, which will ride low in the sky on spring mornings as seen from the Northern Hemisphere. That’s why this shower favors the Southern Hemisphere. It’s often that hemisphere’s best meteor shower of the year.

June 2024 daytime meteor shower … the Arietids

Most meteor showers are easy to observe. Just find a dark sky, and look up! But what about meteor showers that happen in the daytime, when the sun is up? The Arietids are sometimes said to be the most active daytime meteor shower. In 2024, their predicted** peak will be the morning of June 7. You might catch some Arietids that morning in the dark hour before dawn.

When to watch: Watch from May 29 to June 17. There’s a predicted** peak on June 7, 2024. Watch for them in the sunrise direction in the dark hour before dawn breaks.
Nearest moon phase: In 2024, a new moon occurs at 12:38 UTC on June 6. So the mornings around the peak will be completely moon free.
Radiant: The shower’s radiant point – the point in the sky from which the meteors appear to radiate – is in the constellation Aries the Ram. You’ll find this constellation in the east before sunrise.
Duration of shower: May 29 to June 17.
Expected meteors at peak: This is tricky for daytime meteor showers because once the sun comes up, you won’t be able to see them. But the Arietids have a strong zenithal hourly rate (ZHR)! Meteor counts with radar and radio echoes have indicated a rate of 60 meteors per hour, and perhaps as high as 200 meteors per hour.
Note: The Arietids are sometimes said to be the most active daytime meteor shower.

Late July to mid-August 2024 meteors … the Delta Aquariids

Predicted peak: The peak is predicted** for July 30, 2024, at 15:16 UTC. But this shower doesn’t have a noticeable peak. It rambles along steadily from late July through early August, joining forces with the August Perseids.
When to watch: Watch late July through early August, mid-evening to dawn.
Duration of shower: July 18 to August 21.
Radiant: Rises in mid-evening, highest around 2 a.m. and low in the sky by dawn. See chart below.
Nearest moon phase: In 2024, last quarter moon falls at 2:51 UTC on August 1. Take advantage of the moon-free evenings in late July for watching the Delta Aquariids (and the early Perseids).
Expected meteors at peak, under ideal conditions: The Delta Aquariids’ maximum hourly rate can reach 15 to 20 meteors in a dark sky with no moon. You’ll typically see plenty of Delta Aquariids mixed in with the Perseids, if you’re watching in early August.
Note: Like May’s Eta Aquariids, July’s Delta Aquariids favors the Southern Hemisphere. Skywatchers at high northern latitudes tend to discount it. But the shower can be excellent from latitudes like those in the southern U.S. Delta Aquariid meteors tend to be fainter than Perseid meteors. So a moon-free dark sky is essential. About 5% to 10% of the Delta Aquariid meteors leave persistent trains, glowing ionized gas trails that last a second or two after the meteor has passed.

Read more: All you need to know about Delta Aquariid meteors

Mid-July to mid-August 2024 meteors … the Perseids

Predicted peak: The peak is predicted** for August 12, 2024, at 14:00 UTC. So the mornings of August 11, 12 and 13 are probably your best bet.
When to watch: The moon will be a 1st quarter and 50% illuminated during 2024’s peak of the Perseid meteor shower. So the best time to watch for Perseids will be starting around midnight until dawn. This shower rises to a peak gradually, then falls off rapidly. And Perseid meteors tend to strengthen in number as late night deepens into the wee hours before dawn. The shower is often best just before dawn.
Radiant: The radiant rises in the middle of the night and is highest at dawn. See chart below.
Nearest moon phase: First quarter moon falls at 15:19 UTC on August 12. And a 1st quarter moon sets around midnight, so you’ll have dark skies after then until dawn.
Duration of shower: July 14 to September 1.
Expected meteors at peak, under ideal conditions: Under a dark sky with no moon, skywatchers frequently report 90 meteors per hour, or more. In 2023, the waning crescent moon will not interfere with the meteor shower.
Note: The August Perseid meteor shower is rich and steady, from early August through the peak. The meteors are colorful. And they frequently leave persistent trains. All of these factors make the Perseid shower perhaps the most beloved meteor shower for the Northern Hemisphere.

Read more: All you need to know about Perseid meteors

Early October meteors … the Draconids

Predicted peak: The peak is predicted** for October 8, 2024, at 3 UTC.
When to watch: The best time to watch the Draconids in 2024 is the evening of October 7 through the wee hours of the morning on October 8. The waxing crescent moon (27% illuminated) will set before 9 p.m. your local time. So you can watch for meteors in a moonless sky.
Overall duration of shower: October 6 through 10.
Radiant: Highest in the sky in the evening hours. See chart below.
Nearest moon phase: First quarter moon is 18:55 UTC on October 10.
Expected meteors at peak, under ideal conditions: Under a dark sky with no moon, you might catch 10 Draconid meteors per hour.
Note: The Draconid shower is a real oddity, in that the radiant point stands highest in the sky as darkness falls. That means that, unlike many meteor showers, more Draconids are likely to fly in the evening hours than in the morning hours after midnight. This shower is usually a sleeper, producing only a handful of languid meteors per hour in most years. But watch out if the Dragon awakes! In rare instances, fiery Draco has been known to spew forth many hundreds of meteors in a single hour. That possibility keeps many skywatchers outside – even in moonlight – during this shower.

Read more: All you need to know about Draconid meteors

Late October meteors … the Orionids

Predicted peak: The peak is predicted** for October 20, 2024, at 18:14 UTC.
When to watch: Watch for Orionid meteors on both the mornings of October 20 and 21, starting after midnight through the wee hours before dawn.
Overall duration of shower: September 26 to November 22.
Radiant: The radiant rises before midnight and is highest in the sky around 2 a.m. See chart below.
Nearest moon phase: The full moon falls at 11:26 UTC on October 17. So, at the Orionids’ peak, the the waning gibbous moon will interfere with the meteor shower.
Expected meteors at peak, under ideal conditions: Under a dark sky with no moon, the Orionids exhibit a maximum of about 10 to 20 meteors per hour.
Note: These fast-moving meteors occasionally leave persistent trains. The Orionids sometimes produce bright fireballs.

Read more: Everything you need to know Orionid meteors

October into early November … the South and North Taurids

Predicted peak: The South Taurids’ predicted** peak is November 5, 2024, at 7:00 UTC. The North Taurids’ predicted** peak is November 12, 2024, at 6:00 UTC. Both the South and North Taurids don’t have very definite peaks. They ramble along in October and November and are especially noticeable from late October into early November, when they overlap.
When to watch: Best around midnight, and on the days around November 5 when the moon won’t interfere.
Overall duration of shower: The South Taurids run from about September 23 to November 12. North Taurids are active from about October 13 to December 2.
Radiant: Rises in early evening, highest in the sky around midnight. See chart below.
Nearest moon phases: In 2024, the first quarter moon falls on November 9. The new moon is November 1, and it’s before the predicted peak of the South Taurids on November 5, so the days around then will be the best days to watch for Taurid meteors. However, the waxing crescent moon – 3 days before a full moon – will interfere with most meteors around the November 12 peak of the North Taurids. You’ll catch Taurid meteors throughout October and November. Visit Sunrise Sunset Calendars to see moon rising times for your location. Be sure to check the moon rising time box.
Expected meteors at peak, under ideal conditions: Under dark skies with no moon, both the South and North Taurid meteor showers produce about five meteors per hour (10 total when they overlap). Also, watch for fireballs.
Note: Taurid meteors tend to be slow-moving but sometimes very bright. The showers sometimes produce fireballs, which made their cyclical reappearance in 2022. The American Meteor Society pointed to “a seven-year periodicity” with Taurid fireballs. 2008 and 2015 both produced them. 2022 did as well. The Taurid fireball display, in 2015, was really fun! Photos and video of 2015 Taurid fireballs here.

Mid-November meteors … the Leonids

https://earthsky.org/wp-admin/edit.php
Predicted peak: The peak is predicted** for November 18, 2024, at 5:00 UTC.
When to watch: Watch late on the night of November 17 until dawn on November 18. The morning of November 17 might be worthwhile, too.
Duration of shower: November 3 through December 2.
Radiant: Rises around midnight, highest in the sky at dawn.
Nearest moon phase: In 2024, the full moon falls on November 15. So the bright waning gibbous moon will wash out some meteors in 2024.
Expected meteors at peak, under ideal conditions: Under a dark sky with no moon, you might see 10 to 15 Leonid meteors per hour.
Note: The famous Leonid meteor shower produced one of the greatest meteor storms in living memory. Rates were as high as thousands of meteors per minute during a 15-minute span on the morning of November 17, 1966. That night, Leonid meteors did, briefly, fall like rain. Some who witnessed it had a strong impression of Earth moving through space, fording the meteor stream. Leonid meteor storms sometimes recur in cycles of 33 to 34 years. But the Leonids around the turn of the century – while wonderful for many observers – did not match the shower of 1966. And, in most years, the Lion whimpers rather than roars.

Early to mid-December meteors … the Geminids

Predicted peak: is predicted** for December 13, 2024, at 21:00 UTC.
When to watch: Since the radiant rises in mid-evening, you can watch for Geminids all night around the peak dates of December 13. However, an almost full moon will compete with the Geminids in 2024. Luckily, a lot of Geminid meteors are bright. Find a way to block out the bright moon when watching the sky.
Overall duration of shower: November 19 to December 24.
Radiant: Rises in mid-evening, highest around 2 a.m. See chart below.
Nearest moon phase: In 2024, the full moon falls on December 15. So there will be a moonlit sky during the peak of the 2023 Geminid meteor shower.
Expected meteors at peak, under ideal conditions: Under a dark sky with no moon, you might catch 120 Geminid meteors per hour.
Note: The bold, white, bright Geminids give us one of the Northern Hemisphere’s best showers, especially in years when there’s no moon. They’re also visible, at lower rates, from the Southern Hemisphere. The meteors are plentiful, rivaling the August Perseids.
