Moon rises at sunrise and sets at sunset. It's part facing the Earth is completely in shadow.
Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1906" and ∠1949".
Next Full Moon is the Cold Moon of December 2023 after 13 days on 27 December 2023 at 00:33.
There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.
At 23:32 on this date the Moon completes the old and enters a new synodic month with lunation 296 of Meeus index or 1249 from Brown series.
29 days, 12 hours and 25 minutes is the length of new lunation 296. 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°).
8 days after point of apogee on 4 December 2023 at 18:42 in ♍ Virgo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 3 days, until it get to the point of next perigee on 16 December 2023 at 18:53 in ♒ Aquarius.
Moon is 376 092 km (233 693 mi) away from Earth on this date. Moon moves closer next 3 days until perigee, when Earth-Moon distance will reach 367 900 km (228 602 mi).
4 days after its descending node on 8 December 2023 at 15:24 in ♎ Libra, the Moon is following the southern part of its orbit for the next 8 days, until it will cross the ecliptic from South to North in ascending node on 21 December 2023 at 13:54 in ♈ Aries.
19 days after beginning of current draconic month in ♈ Aries, the Moon is moving from the second to the final part of it.
At 21:51 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-28.151°. Next 13 days the lunar orbit will move in opposite northward direction to face North declination of ∠28.131° in its northern standstill point on 26 December 2023 at 21:50 in ♊ Gemini.
The Moon is in New Moon geocentric conjunction with the Sun on this date and this alignment forms Sun-Moon-Earth syzygy.
