Moderate tide
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.
Lunation 391 / 1344
The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 391 of Meeus index or 1344 from Brown series.
Synodic month length 29.59 days
Length of current 391 lunation is 29 days, 14 hours and 15 minutes. It is 41 minutes longer than next lunation 392 length.
Lunation length longer than mean
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.
Lunar orbit position on
True anomaly ∠213.5°
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°).
Moon after perigee
2 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 8 days, until it get to the point of next apogee on 11 September 2031 at 11:54 in ♋ Cancer.
Distance to Moon 373 835 km
Moon is 373 835 km (232 290 mi) away from Earth on this date. Moon moves farther next 8 days until apogee, when Earth-Moon distance will reach 405 006 km (251 659 mi).
Moon before descending node
8 days after its ascending node on 25 August 2031 at 01:21 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 4 days, until it will cross the ecliptic from North to South in descending node on 6 September 2031 at 16:34 in ♉ Taurus.
Draconic month
8 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
Moon before northern standstill
6 days after previous South standstill on 26 August 2031 at 23:55 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.731°. Next 6 days the lunar orbit moves northward to face North declination of ∠20.623° in the next northern standstill on 8 September 2031 at 23:27 in ♊ Gemini.
Syzygy in 14 days
After 14 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.
