Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 28 November 2031 at 23:18.

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 ∠7° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1777"

Lunar disc appears visually 9.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1777" and ∠1946".

Beaver Moon before 2 days

Next Full Moon is the Cold Moon of December 2031 after 27 days on 28 December 2031 at 17:33.

Upcoming main Moon phases

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Lunation 394 / 1347

The Moon is 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 394 of Meeus index or 1347 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.5 days

The length of the lunation is 29 days, 11 hours and 56 minutes. It is 55 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 48 minutes shorter than the mean synodic month length. It is 5 hours and 21 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠312.6°

At the beginning of the lunation cycle the true anomaly is ∠312.6°. At the beginning of next synodic month the true anomaly is going to be ∠334.7°.

Moon before perigee

13 days after point of perigee on 17 November 2031 at 22:07 in ♐ Sagittarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next apogee on 3 December 2031 at 22:35 in ♌ Leo.

Previous perigeeNext apogee

Distance to Moon 403 397 km

The Moon is 403 397 km (250 659 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 405 355 km (251 876 mi).

Moon after descending node

3 days after descending node on 27 November 2031 at 14:01 in ♉ Taurus. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 12 December 2031 at 01:37 in ♏ Scorpio.

Draconic month

16 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

1 day since the previous standstill on 30 November 2031 at 00:08 in ♊ Gemini when the Moon has reached North declination of ∠20.350°, the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-20.356° at the point of next southern standstill on 14 December 2031 at 04:45 in ♐ Sagittarius.

Syzygy in 12 days

In 12 days on 14 December 2031 at 09:06 in ♐ Sagittarius 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.
