Moon phase and lunation details

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 16 January 2031 at 12:47.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♑ Capricorn

Moon is passing about ∠8° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1971"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1950".

Snow Moon after 17 days

Next Full Moon is the Snow Moon of February 2031 after 17 days on 7 February 2031 at 12:46.

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 383 / 1336

The Moon is 27 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 383 of Meeus index or 1336 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.46 days

The length of the lunation is 29 days, 10 hours and 59 minutes. It is 19 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 1 hour and 45 minutes shorter than the mean synodic month length. It is 4 hours and 24 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠5.3°

At the beginning of the lunation cycle the true anomaly is ∠5.3°. At the beginning of next synodic month the true anomaly is going to be ∠21.6°.

Moon at perigee

Moon is at perigee at 21:41. It is 15 days after previous apogee on 6 January 2031 at 11:00 in ♊ Gemini. Lunar orbit is going to widen while the Moon is moving away from the Earth over the next 12 days, until point of next apogee on 2 February 2031 at 23:45 in ♊ Gemini.

Previous apogeeNext apogee

Distance to Moon 359 637 km

This perigee Moon is 359 637 km (223 468 mi) away from Earth. It is 2 871 km closer than the mean perigee distance, but it is still 10 719 km further than the closest perigee of 21st century.

Moon after ascending node

2 days after ascending node on 19 January 2031 at 08:51 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following 10 days, until the lunar orbit crosses from North to South in descending node on 1 February 2031 at 09:25 in ♊ Gemini.

Draconic month

2 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the beginning to the first part of the cycle.

Moon after southern standstill

1 day since the previous standstill on 20 January 2031 at 05:10 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.824°, the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠21.745° at the point of next northern standstill on 2 February 2031 at 12:52 in ♊ Gemini.

Previous standstillNext standstill

Syzygy in 1 day

In 1 day on 23 January 2031 at 04:31 in ♒ Aquarius 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.
