Moon phase and lunation details
5 days after Full Moon
Previous main lunar phase is the Full Moon before 5 days on 1 September 2031 at 09:20.
Moonrise and moonset
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Moon in ♉ Taurus
Moon is passing about ∠19° of ♉ Taurus tropical zodiac sector.
Apparent angular diameter ∠1824"
Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1824" and ∠1904".
Harvest Moon before 5 days
Next Full Moon is the Harvest Moon of September 2031 after 24 days on 30 September 2031 at 18:58.
Upcoming main Moon phases
- Last Quarter in Gemini ♊ on 8 September 2031 at 16:14
- New Moon in Virgo ♍ on 16 September 2031 at 18:47
- First Quarter in Capricorn ♑ on 24 September 2031 at 01:20

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 20 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
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
6 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 4 days, until the Moon reaches the point of next apogee on 11 September 2031 at 11:54 in ♋ Cancer.
Distance to Moon 392 877 km
The Moon is 392 877 km (244 122 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 405 006 km (251 659 mi).
Moon in descending node
Moon is in descending node in ♉ Taurus at 16:34 crossing the ecliptic from North to South to meet ascending node 14 days later on 21 September 2031 at 02:24 in ♏ Scorpio.
Draconic month
12 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the middle to the last part of the cycle.
Moon before northern standstill
10 days since the previous standstill on 26 August 2031 at 23:55 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.731°, the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠20.623° at the point of next northern standstill on 8 September 2031 at 23:27 in ♊ Gemini.
Syzygy in 10 days
In 10 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.
