Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 53% and getting smaller. The 21 days old Moon is in ♊ Gemini.
* The exact date and time of this Last Quarter phase is on 20 September 2057 at 20:25 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing about ∠24° of ♊ Gemini tropical zodiac sector.
Lunar disc appears visually 7.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1911".
Next Full Moon is the Hunter Moon of October 2057 after 22 days on 12 October 2057 at 15:01.
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 713 of Meeus index or 1666 from Brown series.
Length of current 713 lunation is 29 days, 12 hours and 6 minutes. It is 47 minutes longer than next lunation 714 length.
Length of current synodic month is 38 minutes shorter than the mean length of synodic month, but it is still 5 hours and 31 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠255.9°. At the beginning of next synodic month true anomaly will be ∠291.1°. 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°).
11 days after point of perigee on 8 September 2057 at 19:57 in ♑ Capricorn. 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 21 September 2057 at 02:28 in ♋ Cancer.
Moon is 405 307 km (251 846 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 404 133 km (251 117 mi).
Moon is in ascending node in ♊ Gemini at 21:22 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 4 October 2057 at 10:59 in ♐ Sagittarius.
At 21:22 on this date the Moon is completing its previous draconic month and is entering the new one.
12 days after previous South standstill on 8 September 2057 at 05:28 in ♑ Capricorn, when Moon has reached southern declination of ∠-23.933°. Next day the lunar orbit moves northward to face North declination of ∠24.051° in the next northern standstill on 21 September 2057 at 22:51 in ♋ Cancer.
After 8 days on 28 September 2057 at 16:00 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
