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 ∠10° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 7.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1802" and ∠1949".
Next Full Moon is the Wolf Moon of January 2026 after 20 days on 3 January 2026 at 10:03.
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 23 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 320 of Meeus index or 1273 from Brown series.
Length of current 320 lunation is 29 days, 18 hours and 56 minutes. This is the year's longest synodic month of 2025. It is 47 minutes longer than next lunation 321 length.
Length of current synodic month is 6 hours and 12 minutes longer than the mean length of synodic month, but it is still 51 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠181.4°. At the beginning of next synodic month true anomaly will be ∠207°. 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 perigee on 4 December 2025 at 11:06 in ♊ Gemini. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 17 December 2025 at 06:09 in ♏ Scorpio.
Moon is 397 700 km (247 119 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 406 324 km (252 478 mi).
2 days after its descending node on 11 December 2025 at 07:35 in ♍ Virgo, the Moon is following the southern part of its orbit for the next 12 days, until it will cross the ecliptic from South to North in ascending node on 25 December 2025 at 22:03 in ♓ Pisces.
14 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the second to the final part of it.
7 days after previous North standstill on 5 December 2025 at 21:51 in ♊ Gemini, when Moon has reached northern declination of ∠28.263°. Next 6 days the lunar orbit moves southward to face South declination of ∠-28.233° in the next southern standstill on 19 December 2025 at 23:18 in ♐ Sagittarius.
After 6 days on 20 December 2025 at 01:43 in ♐ Sagittarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
