Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 42% and getting smaller. The 22 days old Moon is in ♊ Gemini.
* The exact date and time of this Last Quarter phase is on 8 September 2031 at 16:14 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1778" and ∠1905".
Next Full Moon is the Harvest Moon of September 2031 after 21 days on 30 September 2031 at 18:58.
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 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 391 of Meeus index or 1344 from Brown series.
Length of current 391 lunation is 29 days, 14 hours and 15 minutes. It is 41 minutes longer than next lunation 392 length.
Length of current synodic month is 1 hour and 31 minutes longer than the mean length of synodic month, but it is still 5 hours and 32 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠213.5°. At the beginning of next synodic month true anomaly will be ∠245.2°. 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°).
9 days after point of perigee on 30 August 2031 at 12:53 in ♒ Aquarius. 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 11 September 2031 at 11:54 in ♋ Cancer.
Moon is 403 068 km (250 455 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 405 006 km (251 659 mi).
2 days after its descending node on 6 September 2031 at 16:34 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 11 days, until it will cross the ecliptic from South to North in ascending node on 21 September 2031 at 02:24 in ♏ Scorpio.
15 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.
1 day after previous North standstill on 8 September 2031 at 23:27 in ♊ Gemini, when Moon has reached northern declination of ∠20.623°. Next 13 days the lunar orbit moves southward to face South declination of ∠-20.501° in the next southern standstill on 23 September 2031 at 05:46 in ♐ Sagittarius.
After 7 days on 16 September 2031 at 18:47 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
