Crescent ♏ Scorpio
Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 50% and getting smaller. The 22 days old Moon is in ♎ Libra.
* The exact date and time of this Last Quarter phase is on 16 January 2031 at 12:47 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Lunar disc appears visually 1.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1921" and ∠1950".
Next Full Moon is the Snow Moon of February 2031 after 22 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 22 days old. Earth's natural satellite is moving through the last 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°).
10 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 5 days, until it get to the point of next perigee on 21 January 2031 at 21:41 in ♑ Capricorn.
Moon is 373 193 km (231 891 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 359 637 km (223 468 mi).
11 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 2 days, until it will cross the ecliptic from South to North in ascending node on 19 January 2031 at 08:51 in ♐ Sagittarius.
24 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.
10 days after previous North standstill on 6 January 2031 at 05:22 in ♊ Gemini, when Moon has reached northern declination of ∠21.889°. Next 3 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.
After 6 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.
