Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 27 December 2023 at 00:33.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♋ Cancer

Moon is passing about ∠24° of ♋ Cancer tropical zodiac sector.

Cold Moon before 1 day

Next Full Moon is the Wolf Moon of January 2024 after 28 days on 25 January 2024 at 17:54.

Upcoming main Moon phases

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 296 / 1249

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 296 of Meeus index or 1249 from Brown series.

Synodic month length 29.52 days

The length of the lunation is 29 days, 12 hours and 25 minutes. It is 1 hour and 23 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 19 minutes shorter than the mean synodic month length. It is 5 hours and 50 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠303.6°

At the beginning of the lunation cycle the true anomaly is ∠303.6°. At the beginning of next synodic month the true anomaly is going to be ∠328°.

Moon before perigee

11 days after point of perigee on 16 December 2023 at 18:53 in ♒ Aquarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next apogee on 1 January 2024 at 15:28 in ♍ Virgo.

Previous perigeeNext apogee

Distance to Moon 398 470 km

The Moon is 398 470 km (247 598 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 404 911 km (251 600 mi).

Moon after ascending node

6 days after ascending node on 21 December 2023 at 13:54 in ♈ Aries. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 4 January 2024 at 18:52 in ♎ Libra.

Moon after northern standstill

1 day since the previous standstill on 26 December 2023 at 21:50 in ♊ Gemini when the Moon has reached North declination of ∠28.131°, the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-28.164° at the point of next southern standstill on 10 January 2024 at 07:04 in ♑ Capricorn.

Syzygy in 13 days

In 13 days on 11 January 2024 at 11:57 in ♑ Capricorn the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
