Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon in ♋ Cancer

Moon is passing about ∠16° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1769"

Lunar disc appears visually 8.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1920".

Pink Moon after 7 days

Next Full Moon is the Pink Moon of April 2031 after 7 days on 7 April 2031 at 17:21.

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 386 / 1339

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 386 of Meeus index or 1339 from Brown series.

Synodic month length 29.55 days

The length of the lunation is 29 days, 13 hours and 8 minutes. It is 1 hour and 12 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 longer than mean

The length of the current synodic month is 24 minutes longer than the mean synodic month length. It is 6 hours and 39 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠70.3°

At the beginning of the lunation cycle the true anomaly is ∠70.3°. At the beginning of next synodic month the true anomaly is going to be ∠106.4°.

Moon after apogee

1 day after point of apogee on 30 March 2031 at 15:24 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next perigee on 11 April 2031 at 19:13 in ♐ Sagittarius.

Distance to Moon 405 088 km

The Moon is 405 088 km (251 710 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 367 996 km (228 662 mi).

Moon after descending node

3 days after descending node on 27 March 2031 at 14:22 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 10 April 2031 at 14:56 in ♏ Scorpio.

Draconic month

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

Moon after northern standstill

2 days since the previous standstill on 29 March 2031 at 04:58 in ♊ Gemini when the Moon has reached North declination of ∠21.242°, the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-21.160° at the point of next southern standstill on 12 April 2031 at 00:31 in ♐ Sagittarius.

Syzygy in 7 days

In 7 days on 7 April 2031 at 17:21 in ♎ Libra 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.
