Previous main lunar phase is the Full Moon before 2 days on 20 October 2021 at 14:57.
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Moon is passing first ∠2° of ♊ Gemini tropical zodiac sector.
Lunar disc appears visually 8.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1929".
Next Full Moon is the Beaver Moon of November 2021 after 26 days on 19 November 2021 at 08:58.
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 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 269 of Meeus index or 1222 from Brown series.
Length of current 269 lunation is 29 days, 10 hours and 9 minutes. This is the year's shortest synodic month of 2021. It is 19 minutes shorter than next lunation 270 length.
Length of current synodic month is 2 hours and 35 minutes shorter than the mean length of synodic month, but it is still 3 hours and 34 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠323.3°. At the beginning of next synodic month true anomaly will be ∠342.3°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
14 days after point of perigee on 8 October 2021 at 17:28 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 24 October 2021 at 15:30 in ♊ Gemini.
Moon is 405 221 km (251 793 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 405 616 km (252 038 mi).
Moon is in ascending node in ♊ Gemini at 11:47 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 13 days to meet descending node on 6 November 2021 at 03:38 in ♐ Sagittarius.
At 11:47 on this date the Moon is completing its previous draconic month and is entering the new one.
11 days after previous South standstill on 12 October 2021 at 09:09 in ♑ Capricorn, when Moon has reached southern declination of ∠-26.204°. Next 3 days the lunar orbit moves northward to face North declination of ∠26.291° in the next northern standstill on 26 October 2021 at 16:04 in ♋ Cancer.
After 12 days on 4 November 2021 at 21:15 in ♏ Scorpio, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
