Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 28 December 2031 at 17:33.

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 leaving the last ∠2° of ♋ Cancer tropical zodiac sector and will enter ♌ Leo later.

Apparent angular diameter ∠1768"

Lunar disc appears visually 9.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1951".

Cold Moon before 1 day

Next Full Moon is the Wolf Moon of January 2032 after 28 days on 27 January 2032 at 12:52.

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 16 days old. Earth's natural satellite is moving from the middle to the last 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

14 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 day, until the Moon reaches the point of next apogee on 31 December 2031 at 13:16 in ♌ Leo.

Previous perigeeNext apogee

Distance to Moon 405 304 km

The Moon is 405 304 km (251 844 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 406 203 km (252 403 mi).

Moon after descending node

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

Draconic month

18 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 after northern standstill

3 days since the previous standstill on 27 December 2031 at 07:41 in ♊ Gemini when the Moon has reached North declination of ∠20.355°, the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-20.298° at the point of next southern standstill on 10 January 2032 at 16:49 in ♐ Sagittarius.

Syzygy in 13 days

In 13 days on 12 January 2032 at 20:07 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.
