Moon rises at sunrise and sets at sunset. It's part facing the Earth is completely in shadow.
Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1790" and ∠1896".
Next Full Moon is the Harvest Moon of September 2031 after 13 days on 1 September 2031 at 09:20.
There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.
At 04:32 on this date the Moon completes the old and enters a new synodic month with lunation 391 of Meeus index or 1344 from Brown series.
29 days, 14 hours and 15 minutes is the length of new lunation 391. 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°).
3 days after point of apogee on 14 August 2031 at 21:37 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 12 days, until it get to the point of next perigee on 30 August 2031 at 12:53 in ♒ Aquarius.
Moon is 400 454 km (248 831 mi) away from Earth on this date. Moon moves closer next 12 days until perigee, when Earth-Moon distance will reach 361 684 km (224 740 mi).
7 days after its descending node on 10 August 2031 at 14:10 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 6 days, until it will cross the ecliptic from South to North in ascending node on 25 August 2031 at 01:21 in ♏ Scorpio.
20 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.
5 days after previous North standstill on 12 August 2031 at 15:58 in ♊ Gemini, when Moon has reached northern declination of ∠20.868°. Next 8 days the lunar orbit moves southward to face South declination of ∠-20.731° in the next southern standstill on 26 August 2031 at 23:55 in ♐ Sagittarius.
The Moon is in New Moon geocentric conjunction with the Sun on this date and this alignment forms Sun-Moon-Earth syzygy.
