Lunar disc appears visually 2.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1856" and ∠1910".
Next Full Moon is the Harvest Moon of September 2031 after 12 days on 30 September 2031 at 18:58.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
The Moon is 2 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 392 of Meeus index or 1345 from Brown series.
Length of current 392 lunation is 29 days, 13 hours and 34 minutes. It is 45 minutes longer than next lunation 393 length.
Length of current synodic month is 50 minutes longer than the mean length of synodic month, but it is still 6 hours and 13 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠245.2°. At the beginning of next synodic month true anomaly will be ∠281.8°. 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°).
7 days after point of apogee on 11 September 2031 at 11:54 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 27 September 2031 at 07:09 in ♒ Aquarius.
Moon is 386 276 km (240 021 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 366 841 km (227 944 mi).
11 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 2 days, until it will cross the ecliptic from South to North in ascending node on 21 September 2031 at 02:24 in ♏ Scorpio.

9 days after previous North standstill on 8 September 2031 at 23:27 in ♊ Gemini, when Moon has reached northern declination of ∠20.623°. Next 4 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 12 days on 30 September 2031 at 18:58 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
