Previous main lunar phase is the First Quarter before 1 day on 19 December 2023 at 18:39.
Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.
Moon is passing about ∠21° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 0.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1945" and ∠1951".
Next Full Moon is the Cold Moon of December 2023 after 5 days on 27 December 2023 at 00:33.
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 9 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 296 of Meeus index or 1249 from Brown series.
Length of current 296 lunation is 29 days, 12 hours and 25 minutes. It is 1 hour and 23 minutes longer than next lunation 297 length.
Length of current synodic month is 19 minutes shorter than the mean length of synodic month, but it is still 5 hours and 50 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠303.6°. At the beginning of next synodic month true anomaly will be ∠328°. 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°).
4 days after point of perigee on 16 December 2023 at 18:53 in ♒ Aquarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 11 days, until it get to the point of next apogee on 1 January 2024 at 15:28 in ♍ Virgo.
Moon is 368 475 km (228 960 mi) away from Earth on this date. Moon moves farther next 11 days until apogee, when Earth-Moon distance will reach 404 911 km (251 600 mi).
Moon is in ascending node in ♈ Aries at 13:54 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 14 days to meet descending node on 4 January 2024 at 18:52 in ♎ Libra.
At 13:54 on this date the Moon is completing its previous draconic month and is entering the new one.
7 days after previous South standstill on 13 December 2023 at 21:51 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.151°. Next 5 days the lunar orbit moves northward to face North declination of ∠28.131° in the next northern standstill on 26 December 2023 at 21:50 in ♊ Gemini.
After 5 days on 27 December 2023 at 00:33 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
