Previous main lunar phase is the Last Quarter before 4 days on 16 January 2031 at 12:47.
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 ∠8° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1950".
Next Full Moon is the Snow Moon of February 2031 after 17 days on 7 February 2031 at 12:46.
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.
The Moon is 27 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.
Length of current 383 lunation is 29 days, 10 hours and 59 minutes. It is 19 minutes shorter than next lunation 384 length.
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.
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 is reaching point of perigee on this date at 21:41, this is 15 days after last apogee on 6 January 2031 at 11:00 in ♊ Gemini. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 12 days ahead, until it will get to the point of next apogee on 2 February 2031 at 23:45 in ♊ Gemini.
This perigee Moon is 359 637 km (223 468 mi) away from Earth. It is 2 871 km closer than the mean perigee distance, but it is still 10 719 km farther than the closest perigee of 21st century.
2 days after its ascending node on 19 January 2031 at 08:51 in ♐ Sagittarius, 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 1 February 2031 at 09:25 in ♊ Gemini.
2 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.
1 day after previous South standstill on 20 January 2031 at 05:10 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.824°. Next 12 days the lunar orbit moves northward to face North declination of ∠21.745° in the next northern standstill on 2 February 2031 at 12:52 in ♊ Gemini.
After 1 day 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.
