Moon rises at sunrise and sets at sunset. It's part facing the Earth is completely in shadow.
Moon is passing about ∠15° of ♐ Sagittarius tropical zodiac sector.
Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1973" and ∠1947".
Next Full Moon is the Cold Moon of December 2021 after 14 days on 19 December 2021 at 04:36.
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 07:43 on this date the Moon completes the old and enters a new synodic month with lunation 271 of Meeus index or 1224 from Brown series.
29 days, 10 hours and 50 minutes is the length of new lunation 271. It is 23 minutes shorter than next lunation 272 length.
Length of current synodic month is 1 hour and 54 minutes shorter than the mean length of synodic month, but it is still 4 hours and 15 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠358.3°. At beginning of next synodic month true anomaly will be ∠13.9°. 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 10:01, this is 13 days after last apogee on 21 November 2021 at 02:14 in ♊ Gemini. 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 18 December 2021 at 02:16 in ♊ Gemini.
This perigee Moon is 356 794 km (221 702 mi) away from Earth. This is the year's closest perigee of 2021. It is 5 714 km closer than the mean perigee distance, but it is still 369 km farther than the closest perigee of 21st century.
1 day after its descending node on 3 December 2021 at 14:58 in ♏ Scorpio, the Moon is following the southern part of its orbit for the next 12 days, until it will cross the ecliptic from South to North in ascending node on 17 December 2021 at 00:12 in ♊ Gemini.
14 days after beginning of current draconic month in ♉ Taurus, the Moon is moving from the second to the final part of it.
11 days after previous North standstill on 22 November 2021 at 22:43 in ♋ Cancer, when Moon has reached northern declination of ∠26.342°. Next day the lunar orbit moves southward to face South declination of ∠-26.331° in the next southern standstill on 6 December 2021 at 02:25 in ♑ Capricorn.
The Moon is in New Moon geocentric conjunction with the Sun on this date and this alignment forms Sun-Moon-Earth syzygy.
