Moon phase and lunation details

2 days after Last Quarter

Previous main lunar phase is the Last Quarter before 2 days on 16 January 2031 at 12:47.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♐ Sagittarius

Moon is passing about ∠8° of ♐ Sagittarius tropical zodiac sector.

Snow Moon after 19 days

Next Full Moon is the Snow Moon of February 2031 after 19 days on 7 February 2031 at 12:46.

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 383 / 1336

The Moon is 25 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 383 of Meeus index or 1336 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.46 days

Length of current 383 lunation is 29 days, 10 hours and 59 minutes. It is 19 minutes shorter than next lunation 384 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 45 minutes shorter than the mean length of synodic month, but it is still 4 hours and 24 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠5.3°

This New Moon true anomaly is ∠5.3°. At beginning of next synodic month true anomaly will be ∠21.6°. 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

13 days after point of apogee on 6 January 2031 at 11:00 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 21 January 2031 at 21:41 in ♑ Capricorn.

Distance to Moon 364 240 km

Moon is 364 240 km (226 328 mi) away from Earth on this date. Moon moves closer next 2 days until perigee, when Earth-Moon distance will reach 359 637 km (223 468 mi).

Moon in ascending node

Moon is in ascending node in ♐ Sagittarius at 08:51 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 12 days to meet descending node on 1 February 2031 at 09:25 in ♊ Gemini.

Previous nodeNext node

New draconic month

At 08:51 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon before southern standstill

13 days after previous North standstill on 6 January 2031 at 05:22 in ♊ Gemini, when Moon has reached northern declination of ∠21.889°. Next day the lunar orbit moves southward to face South declination of ∠-21.824° in the next southern standstill on 20 January 2031 at 05:10 in ♐ Sagittarius.

Syzygy in 3 days

After 3 days on 23 January 2031 at 04:31 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
