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

Length of current 386 lunation is 29 days, 13 hours and 8 minutes. It is 1 hour and 12 minutes shorter than next lunation 387 length.

Lunation length longer than mean

Length of current synodic month is 24 minutes longer than the mean length of synodic month, but it is still 6 hours and 39 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠70.3°

This New Moon true anomaly is ∠70.3°. At beginning of next synodic month true anomaly will be ∠106.4°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after apogee

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

Distance to Moon 405 088 km

Moon is 405 088 km (251 710 mi) away from Earth on this date. Moon moves closer next 11 days until perigee, when Earth-Moon distance will reach 367 996 km (228 662 mi).

Moon after descending node

3 days after its descending node on 27 March 2031 at 14:22 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 10 days, until it will cross the ecliptic from South to North in ascending node on 10 April 2031 at 14:56 in ♏ Scorpio.

Moon after northern standstill

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

Syzygy in 7 days

After 7 days on 7 April 2031 at 17:21 in ♎ Libra, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
