Moonrise and moonset

Moon rises at sunrise and sets at sunset. It's part facing the Earth is completely in shadow.

Moon in ♐ Sagittarius

Moon is passing about ∠24° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter

Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1950" and ∠1949".

Next Full Moon is the Cold Moon of December 2031 after 14 days on 28 December 2031 at 17:33.

Upcoming main Moon phases

Spring tide

There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.

New lunation 395 / 1348

At 09:06 on this date the Moon completes the old and enters a new synodic month with lunation 395 of Meeus index or 1348 from Brown series.


Synodic month length 29.46 days

29 days, 11 hours and 1 minute is the length of new lunation 395. This is the year's shortest synodic month of 2031. It is 43 minutes longer than next lunation 396 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 43 minutes shorter than the mean length of synodic month, but it is still 4 hours and 26 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠334.7°

This lunation true anomaly is ∠334.7°. At the beginning of next synodic month true anomaly will be ∠351.6°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon before perigee

10 days after point of apogee on 3 December 2031 at 22:35 in ♌ Leo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 15 December 2031 at 21:31 in ♑ Capricorn.

Previous apogeeNext perigee

Distance to Moon 367 588 km

Moon is 367 588 km (228 409 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 360 489 km (223 997 mi).

Moon after ascending node

2 days after its ascending node on 12 December 2031 at 01:37 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 10 days, until it will cross the ecliptic from North to South in descending node on 24 December 2031 at 18:44 in ♉ Taurus.

Moon in southern standstill

At 04:45 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-20.356°. Next 12 days the lunar orbit will move in opposite northward direction to face North declination of ∠20.355° in its northern standstill point on 27 December 2031 at 07:41 in ♊ Gemini.
