Previous main lunar phase is the Last Quarter before 4 days on 27 December 2021 at 02:24.
Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.
Moon is passing about ∠8° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1951".
Next Full Moon is the Wolf Moon of January 2022 after 17 days on 17 January 2022 at 23:49.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
The Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 271 of Meeus index or 1224 from Brown series.
Length of current 271 lunation is 29 days, 10 hours and 50 minutes. 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°).
13 days after point of apogee on 18 December 2021 at 02:16 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 1 January 2022 at 23:00 in ♐ Sagittarius.
Moon is 363 571 km (225 913 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 358 037 km (222 474 mi).
Moon is in descending node in ♐ Sagittarius at 01:07 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 12 days to meet ascending node on 13 January 2022 at 04:19 in ♊ Gemini.
14 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the second to the final part of it.
11 days after previous North standstill on 20 December 2021 at 04:32 in ♋ Cancer, when Moon has reached northern declination of ∠26.306°. Next 2 days the lunar orbit moves southward to face South declination of ∠-26.304° in the next southern standstill on 2 January 2022 at 13:35 in ♑ Capricorn.
After 2 days on 2 January 2022 at 18:33 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
