Moon phase and lunation details

6 days after First Quarter

Previous main lunar phase is the First Quarter before 6 days on 21 December 2031 at 00:00.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon in ♊ Gemini

Moon is passing about ∠22° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1794"

Lunar disc appears visually 8.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1794" and ∠1951".

Cold Moon after 1 day

Next Full Moon is the Cold Moon of December 2031 after 1 day on 28 December 2031 at 17:33.

Upcoming main Moon phases

Moderate tide

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 395 / 1348

The Moon is 13 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 395 of Meeus index or 1348 from Brown series.

Synodic month length 29.46 days

The length of the lunation is 29 days, 11 hours and 1 minute. This is the year's shortest synodic month of 2031. It is 43 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 1 hour and 43 minutes shorter than the mean synodic month length. It is 4 hours and 26 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠334.7°

At the beginning of the lunation cycle the true anomaly is ∠334.7°. At the beginning of next synodic month the true anomaly is going to be ∠351.6°.

Moon before perigee

11 days after point of perigee on 15 December 2031 at 21:31 in ♑ Capricorn. 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 31 December 2031 at 13:16 in ♌ Leo.

Previous perigeeNext apogee

Distance to Moon 399 453 km

The Moon is 399 453 km (248 209 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 406 203 km (252 403 mi).

Moon after descending node

2 days after descending node on 24 December 2031 at 18:44 in ♉ Taurus. The Moon is located south of the ecliptic over the following 11 days, until the lunar orbit crosses from South to North in ascending node on 8 January 2032 at 08:58 in ♏ Scorpio.

Draconic month

15 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the second to the final part of the cycle.

Moon at northern standstill

At 07:41 the Moon is meeting its standstill point to reach North declination of ∠20.355°. Over the next 14 days the lunar orbit is going to extend southward to face maximum declination of ∠-20.298° at the point of next standstill in ♐ Sagittarius on 10 January 2032 at 16:49.

Previous standstillNext standstill

Syzygy in 1 day

In 1 day on 28 December 2031 at 17:33 in ♋ Cancer the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
