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 ∠1892" and ∠1951".
Next Full Moon is the Wolf Moon of January 2021 after 15 days on 28 January 2021 at 19:16.
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 05:00 on this date the Moon completes the old and enters a new synodic month with lunation 260 of Meeus index or 1213 from Brown series.
29 days, 14 hours and 5 minutes is the length of new lunation 260. It is 1 hour and 10 minutes shorter than next lunation 261 length.
Length of current synodic month is 1 hour and 21 minutes longer than the mean length of synodic month, but it is still 5 hours and 42 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠53.8°. At beginning of next synodic month true anomaly will be ∠87°. 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 9 January 2021 at 15:39 in ♏ Scorpio. 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 21 January 2021 at 13:11 in ♉ Taurus.
Moon is 378 897 km (235 436 mi) away from Earth on this date. Moon moves farther next 8 days until apogee, when Earth-Moon distance will reach 404 361 km (251 258 mi).
2 days after its descending node on 10 January 2021 at 20:15 in ♐ Sagittarius, 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 24 January 2021 at 21:47 in ♊ Gemini.
15 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the second to the final part of it.
1 day after previous South standstill on 12 January 2021 at 08:18 in ♑ Capricorn, when Moon has reached southern declination of ∠-24.870°. Next 13 days the lunar orbit moves northward to face North declination of ∠24.898° in the next northern standstill on 26 January 2021 at 15:39 in ♋ Cancer.
The Moon is in New Moon geocentric conjunction with the Sun on this date and this alignment forms Sun-Moon-Earth syzygy.
