Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 8 January 2031 at 18:26.

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 ♌ Leo

Moon is passing about ∠21° of ♌ Leo tropical zodiac sector.

Apparent angular diameter ∠1811"

Lunar disc appears visually 7.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1811" and ∠1951".

Wolf Moon before 2 days

Next Full Moon is the Snow Moon of February 2031 after 27 days on 7 February 2031 at 12:46.

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 383 / 1336

The Moon is 17 days old. Earth's natural satellite is moving from the middle to the last 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 after apogee

5 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 10 days, until it get to the point of next perigee on 21 January 2031 at 21:41 in ♑ Capricorn.

Previous apogeeNext perigee

Distance to Moon 395 780 km

Moon is 395 780 km (245 926 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 359 637 km (223 468 mi).

Moon after descending node

6 days after its descending node on 5 January 2031 at 06:37 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 7 days, until it will cross the ecliptic from South to North in ascending node on 19 January 2031 at 08:51 in ♐ Sagittarius.

Draconic month

19 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.

Moon after northern standstill

5 days after previous North standstill on 6 January 2031 at 05:22 in ♊ Gemini, when Moon has reached northern declination of ∠21.889°. Next 8 days 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.

Previous standstillNext standstill

Syzygy in 11 days

After 11 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.
