Moon phase and lunation details
Moonrise and moonset
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon in ♊ Gemini
Moon is leaving the last ∠4° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.
Apparent angular diameter ∠1778"
Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1778" and ∠1905".
Harvest Moon after 21 days
Next Full Moon is the Harvest Moon of September 2031 after 21 days on 30 September 2031 at 18:58.

Neap tide
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.
Lunation 391 / 1344
The Moon is 22 days old. Earth's natural satellite is moving through 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
The length of the lunation is 29 days, 14 hours and 15 minutes. It is 41 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 1 hour and 31 minutes longer than the mean synodic month length. It is 5 hours and 32 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠213.5°
At the beginning of the lunation cycle the true anomaly is ∠213.5°. At the beginning of next synodic month the true anomaly is going to be ∠245.2°.
Moon before perigee
9 days after point of perigee on 30 August 2031 at 12:53 in ♒ Aquarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next day, until the Moon reaches the point of next apogee on 11 September 2031 at 11:54 in ♋ Cancer.
Distance to Moon 403 068 km
The Moon is 403 068 km (250 455 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 405 006 km (251 659 mi).
Moon after descending node
2 days after descending node on 6 September 2031 at 16:34 in ♉ Taurus. The Moon is located south of the ecliptic over the following 11 days, until the lunar orbit crosses from South to North in ascending node on 21 September 2031 at 02:24 in ♏ Scorpio.
Draconic month
15 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 after northern standstill
1 day 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 13 days to face maximum declination of ∠-20.501° at the point of next southern standstill on 23 September 2031 at 05:46 in ♐ Sagittarius.
Syzygy in 7 days
In 7 days on 16 September 2031 at 18:47 in ♍ Virgo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
