Spring tide
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.
New lunation 392 / 1345
At 18:47 on this date the Moon completes the old and enters a new synodic month with lunation 392 of Meeus index or 1345 from Brown series.
Synodic month length 29.57 days
The length of the lunation is 29 days, 13 hours and 34 minutes. It is 45 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
Lunation length longer than mean
The length of the current synodic month is 50 minutes longer than the mean synodic month length. It is 6 hours and 13 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠245.2°
The true anomaly is ∠245.2°. At the beginning of the next synodic month the true anomaly is going to be ∠281.8°.
Moon after apogee
6 days after point of apogee on 11 September 2031 at 11:54 in ♋ Cancer. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next perigee on 27 September 2031 at 07:09 in ♒ Aquarius.
Distance to Moon 390 898 km
The Moon is 390 898 km (242 893 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 366 841 km (227 944 mi).
Moon before ascending node
10 days after descending node on 6 September 2031 at 16:34 in ♉ Taurus. The Moon is located south of the ecliptic over the following 3 days, until the lunar orbit crosses from South to North in ascending node on 21 September 2031 at 02:24 in ♏ Scorpio.
Draconic month
23 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the second to the final part of the cycle.
Moon before southern standstill
8 days since the previous standstill on 8 September 2031 at 23:27 in ♊ Gemini when the Moon has reached North declination of ∠20.623°, the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-20.501° at the point of next southern standstill on 23 September 2031 at 05:46 in ♐ Sagittarius.
Sun-Moon-Earth syzygy
The Moon is in a New Moon geocentric conjunction with the Sun and thus forming Sun-Moon-Earth syzygy alignment.
