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 ∠1973" and ∠1950".
Next Full Moon is the Snow Moon of February 2023 after 15 days on 5 February 2023 at 18:29.
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 20:53 on this date the Moon completes the old and enters a new synodic month with lunation 285 of Meeus index or 1238 from Brown series.
29 days, 10 hours and 13 minutes is the length of new lunation 285. This is the year's shortest synodic month of 2023. It is 4 minutes shorter than next lunation 286 length.
Length of current synodic month is 2 hours and 31 minutes shorter than the mean length of synodic month, but it is still 3 hours and 38 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠360°. At beginning of next synodic month true anomaly will be ∠15.6°. 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°).
Moon is reaching point of perigee on this date at 20:58, this is 13 days after last apogee on 8 January 2023 at 09:19 in ♌ Leo. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 13 days ahead, until it will get to the point of next apogee on 4 February 2023 at 08:55 in ♌ Leo.
This perigee Moon is 356 570 km (221 562 mi) away from Earth. This is the year's closest perigee of 2023. It is 5 938 km closer than the mean perigee distance, but it is still 145 km farther than the closest perigee of 21st century.
5 days after its descending node on 16 January 2023 at 06:32 in ♏ Scorpio, the Moon is following the southern part of its orbit for the next 7 days, until it will cross the ecliptic from South to North in ascending node on 28 January 2023 at 16:05 in ♉ Taurus.
19 days after beginning of current draconic month in ♉ Taurus, the Moon is moving from the second to the final part of it.
1 day after previous South standstill on 20 January 2023 at 05:06 in ♑ Capricorn, when Moon has reached southern declination of ∠-27.461°. Next 11 days the lunar orbit moves northward to face North declination of ∠27.511° in the next northern standstill on 2 February 2023 at 08:18 in ♋ Cancer.
The Moon is in New Moon geocentric conjunction with the Sun on this date and this alignment forms Sun-Moon-Earth syzygy.
