Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 53% and getting smaller. The 21 days old Moon is in ♎ Libra.
* The exact date and time of this Last Quarter phase is on 21 January 2025 at 20:31 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Lunar disc appears visually 9.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1950".
Next Full Moon is the Snow Moon of February 2025 after 22 days on 12 February 2025 at 13:53.
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 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 309 of Meeus index or 1262 from Brown series.
Length of current 309 lunation is 29 days, 14 hours and 9 minutes. It is 2 hours longer than next lunation 310 length.
Length of current synodic month is 1 hour and 25 minutes longer than the mean length of synodic month, but it is still 5 hours and 38 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠272.9°. At the beginning of next synodic month true anomaly will be ∠305.9°. 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°).
Moon is reaching point of apogee on this date at 04:55, this is 13 days after last perigee on 7 January 2025 at 23:34 in ♈ Aries. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 11 days ahead, until it will get to the point of next perigee on 2 February 2025 at 02:43 in ♈ Aries.
This apogee Moon is 404 299 km (251 220 mi) away from Earth. It is 1 109 km farther than the mean apogee distance, but it is still 2 410 km closer than the farthest apogee of 21st century.
2 days after its descending node on 19 January 2025 at 01:48 in ♍ Virgo, the Moon is following the southern part of its orbit for the next 11 days, until it will cross the ecliptic from South to North in ascending node on 1 February 2025 at 22:06 in ♓ Pisces.
15 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the second to the final part of it.
9 days after previous North standstill on 12 January 2025 at 04:30 in ♋ Cancer, when Moon has reached northern declination of ∠28.464°. Next 5 days the lunar orbit moves southward to face South declination of ∠-28.534° in the next southern standstill on 26 January 2025 at 13:27 in ♐ Sagittarius.
After 8 days on 29 January 2025 at 12:36 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
