Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.
Moon is passing about ∠6° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 2.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1844" and ∠1897".
Next Full Moon is the Harvest Moon of September 2031 after 10 days on 1 September 2031 at 09:20.
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 3 days young. Earth's natural satellite is moving from the beginning to the first 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°).
6 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 9 days, until it get to the point of next perigee on 30 August 2031 at 12:53 in ♒ Aquarius.
Moon is 388 762 km (241 566 mi) away from Earth on this date. Moon moves closer next 9 days until perigee, when Earth-Moon distance will reach 361 684 km (224 740 mi).
10 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 3 days, until it will cross the ecliptic from South to North in ascending node on 25 August 2031 at 01:21 in ♏ Scorpio.

8 days after previous North standstill on 12 August 2031 at 15:58 in ♊ Gemini, when Moon has reached northern declination of ∠20.868°. Next 5 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.
After 10 days on 1 September 2031 at 09:20 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
