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 ∠1893" and ∠1949".
Next Full Moon is the Cold Moon of December 2099 after 15 days on 27 December 2099 at 12:58.
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 23:09 on this date the Moon completes the old and enters a new synodic month with lunation 1236 of Meeus index or 2189 from Brown series.
29 days, 13 hours and 47 minutes is the length of new lunation 1236. It is 2 hours and 12 minutes shorter than next lunation 1237 length.
Length of current synodic month is 1 hour and 3 minutes longer than the mean length of synodic month, but it is still 6 hours shorter, compared to 21st century longest.
This New Moon true anomaly is ∠49.8°. At beginning of next synodic month true anomaly will be ∠81.3°. 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°).
3 days after point of perigee on 8 December 2099 at 17:50 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 8 days, until it get to the point of next apogee on 20 December 2099 at 13:16 in ♈ Aries.
Moon is 378 738 km (235 337 mi) away from Earth on this date. Moon moves farther next 8 days until apogee, when Earth-Moon distance will reach 404 339 km (251 245 mi).
6 days after its descending node on 5 December 2099 at 21:04 in ♍ Virgo, the Moon is following the southern part of its orbit for the next 6 days, until it will cross the ecliptic from South to North in ascending node on 19 December 2099 at 01:02 in ♓ Pisces.
20 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the second to the final part of it.
At 13:59 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-28.351°. This is the year's southernmost lunar standstill of 2099. Next 14 days the lunar orbit will move in opposite northward direction to face North declination of ∠28.345° in its northern standstill point on 26 December 2099 at 23:34 in ♊ Gemini.
The Moon is in New Moon geocentric conjunction with the Sun on this date and this alignment forms Sun-Moon-Earth syzygy.
