Moon phase and lunation details

5 days after Last Quarter

Previous main lunar phase is the Last Quarter before 5 days on 14 February 2031 at 22:50.

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 ♒ Aquarius

Moon is passing about ∠16° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1942"

Lunar disc appears visually 0.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1942" and ∠1940".

Worm Moon after 16 days

Next Full Moon is the Worm Moon of March 2031 after 16 days on 9 March 2031 at 04:30.

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 384 / 1337

The Moon is 28 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 384 of Meeus index or 1337 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.47 days

The length of the lunation is 29 days, 11 hours and 18 minutes. It is 42 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 26 minutes shorter than the mean synodic month length. It is 4 hours and 43 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠21.6°

At the beginning of the lunation cycle the true anomaly is ∠21.6°. At the beginning of next synodic month the true anomaly is going to be ∠41.9°.

Moon after perigee

1 day after point of perigee on 19 February 2031 at 00:35 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 10 days, until the Moon reaches the point of next apogee on 2 March 2031 at 18:57 in ♊ Gemini.

Previous perigeeNext apogee

Distance to Moon 369 071 km

The Moon is 369 071 km (229 330 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 404 533 km (251 365 mi).

Moon after ascending node

5 days after ascending node on 15 February 2031 at 11:21 in ♐ Sagittarius. 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 28 February 2031 at 11:02 in ♊ Gemini.

Draconic month

5 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

3 days since the previous standstill on 16 February 2031 at 13:25 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.615°, the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠21.491° at the point of next northern standstill on 1 March 2031 at 20:54 in ♊ Gemini.

Syzygy in 1 day

In 1 day on 21 February 2031 at 15:49 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.
