Previous main lunar phase is the Last Quarter before 6 days on 7 December 2031 at 03:20.
Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.
Moon is passing about ∠9° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 0.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1931" and ∠1949".
Next Full Moon is the Cold Moon of December 2031 after 15 days on 28 December 2031 at 17:33.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
The Moon is 28 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 394 of Meeus index or 1347 from Brown series.
Length of current 394 lunation is 29 days, 11 hours and 56 minutes. It is 55 minutes longer than next lunation 395 length.
Length of current synodic month is 48 minutes shorter than the mean length of synodic month, but it is still 5 hours and 21 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠312.6°. At the beginning of next synodic month true anomaly will be ∠334.7°. 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°).
9 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 2 days, until it get to the point of next perigee on 15 December 2031 at 21:31 in ♑ Capricorn.
Moon is 371 110 km (230 597 mi) away from Earth on this date. Moon moves closer next 2 days until perigee, when Earth-Moon distance will reach 360 489 km (223 997 mi).
1 day 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 11 days, until it will cross the ecliptic from North to South in descending node on 24 December 2031 at 18:44 in ♉ Taurus.
1 day after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
13 days after previous North standstill on 30 November 2031 at 00:08 in ♊ Gemini, when Moon has reached northern declination of ∠20.350°. Next day the lunar orbit moves southward to face South declination of ∠-20.356° in the next southern standstill on 14 December 2031 at 04:45 in ♐ Sagittarius.
After 1 day on 14 December 2031 at 09:06 in ♐ Sagittarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
