Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 55% and getting smaller. The 21 days old Moon is in ♊ Gemini.
* The exact date and time of this Last Quarter phase is on 29 September 2021 at 01:57 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Lunar disc appears visually 7.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1775" and ∠1915".
Next Full Moon is the Hunter Moon of October 2021 after 22 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 21 days old. Earth's natural satellite is moving through 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°).
1 day after point of apogee on 26 September 2021 at 21:44 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 8 October 2021 at 17:28 in ♏ Scorpio.
Moon is 403 886 km (250 963 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 363 388 km (225 799 mi).
2 days after its ascending node on 26 September 2021 at 07:33 in ♊ Gemini, the Moon is following the northern part of its orbit for the next 11 days, until it will cross the ecliptic from North to South in descending node on 9 October 2021 at 19:35 in ♏ Scorpio.
2 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the beginning to the first part of it.
13 days after previous South standstill on 15 September 2021 at 03:48 in ♑ Capricorn, when Moon has reached southern declination of ∠-25.980°. Next day 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 7 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.
