Previous main lunar phase is the Full Moon before 2 days on 20 September 2021 at 23:55.
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 ∠0° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1789" and ∠1913".
Next Full Moon is the Hunter Moon of October 2021 after 27 days on 20 October 2021 at 14:57.
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 268 of Meeus index or 1221 from Brown series.
Length of current 268 lunation is 29 days, 10 hours and 14 minutes. It is 5 minutes longer than next lunation 269 length.
Length of current synodic month is 2 hours and 30 minutes shorter than the mean length of synodic month, but it is still 3 hours and 39 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠297.8°. At the beginning of next synodic month true anomaly will be ∠323.3°. 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°).
12 days after point of perigee on 11 September 2021 at 10:05 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 26 September 2021 at 21:44 in ♊ Gemini.
Moon is 400 626 km (248 937 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 404 641 km (251 432 mi).
10 days after its descending node on 12 September 2021 at 16:35 in ♏ Scorpio, the Moon is following the southern part of its orbit for the next 2 days, until it will cross the ecliptic from South to North in ascending node on 26 September 2021 at 07:33 in ♊ Gemini.
24 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the second to the final part of it.
8 days after previous South standstill on 15 September 2021 at 03:48 in ♑ Capricorn, when Moon has reached southern declination of ∠-25.980°. Next 5 days the lunar orbit moves northward to face North declination of ∠26.109° in the next northern standstill on 29 September 2021 at 08:26 in ♋ Cancer.
After 12 days on 6 October 2021 at 11:05 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
