Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Moon in ♒ Aquarius

Moon is passing about ∠9° of ♒ Aquarius tropical zodiac sector.

Cold Moon after 11 days

Next Full Moon is the Cold Moon of December 2031 after 11 days on 28 December 2031 at 17:33.

Upcoming main Moon phases

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 395 / 1348

The Moon is 4 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 395 of Meeus index or 1348 from Brown series.

Synodic month length 29.46 days

Length of current 395 lunation is 29 days, 11 hours and 1 minute. 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 after perigee

1 day after point of perigee on 15 December 2031 at 21:31 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 14 days, until it get to the point of next apogee on 31 December 2031 at 13:16 in ♌ Leo.

Distance to Moon 363 355 km

Moon is 363 355 km (225 778 mi) away from Earth on this date. Moon moves farther next 14 days until apogee, when Earth-Moon distance will reach 406 203 km (252 403 mi).

Moon after ascending node

5 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 7 days, until it will cross the ecliptic from North to South in descending node on 24 December 2031 at 18:44 in ♉ Taurus.

Moon after southern standstill

3 days after previous South standstill on 14 December 2031 at 04:45 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.356°. Next 9 days the lunar orbit moves northward to face North declination of ∠20.355° in the next northern standstill on 27 December 2031 at 07:41 in ♊ Gemini.

Syzygy in 11 days

After 11 days on 28 December 2031 at 17:33 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
