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 ♐ Sagittarius

Moon is passing about ∠15° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1968"

Lunar disc appears visually 2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1968" and ∠1929".

Worm Moon before 6 days

Next Full Moon is the Pink Moon of April 2031 after 23 days on 7 April 2031 at 17:21.

Upcoming main Moon phases

  • Last Quarter in Sagittarius ♐ on 16 March 2031 at 06:36
  • New Moon in Aries ♈ on 23 March 2031 at 03:49

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 385 / 1338

The Moon is 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 385 of Meeus index or 1338 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.5 days

Length of current 385 lunation is 29 days, 12 hours and 1 minute. It is 1 hour and 8 minutes shorter than next lunation 386 length.

Lunation length shorter than mean

Length of current synodic month is 44 minutes shorter than the mean length of synodic month, but it is still 5 hours and 25 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠41.9°

This New Moon true anomaly is ∠41.9°. At beginning of next synodic month true anomaly will be ∠70.3°. 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 before perigee

12 days after point of apogee on 2 March 2031 at 18:57 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 2 days, until it get to the point of next perigee on 17 March 2031 at 18:58 in ♑ Capricorn.

Previous apogeeNext perigee

Distance to Moon 364 302 km

Moon is 364 302 km (226 367 mi) away from Earth on this date. Moon moves closer next 2 days until perigee, when Earth-Moon distance will reach 369 634 km (229 680 mi).

Moon after ascending node

1 day after its ascending node on 14 March 2031 at 11:38 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 12 days, until it will cross the ecliptic from North to South in descending node on 27 March 2031 at 14:22 in ♉ Taurus.

Draconic month

1 day after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.

Moon in southern standstill

At 19:06 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-21.353°. Next 13 days the lunar orbit will move in opposite northward direction to face North declination of ∠21.242° in its northern standstill point on 29 March 2031 at 04:58 in ♊ Gemini.

Syzygy in 7 days

After 7 days on 23 March 2031 at 03:49 in ♈ Aries, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
