Moon phase and lunation details
Moonrise and moonset
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon in ♐ Sagittarius
Moon is passing about ∠12° of ♐ Sagittarius tropical zodiac sector.
Apparent angular diameter ∠1951"
Lunar disc appears visually 2.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1951" and ∠1899".
Harvest Moon after 5 days
Next Full Moon is the Harvest Moon of September 2031 after 5 days on 1 September 2031 at 09:20.
Upcoming main Moon phases
- Full Moon in Pisces ♓ on 1 September 2031 at 09:20
- 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 8 days young. Earth's natural satellite is moving through the first 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 apogee
11 days after point of apogee on 14 August 2031 at 21:37 in ♋ Cancer. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next perigee on 30 August 2031 at 12:53 in ♒ Aquarius.
Distance to Moon 367 345 km
The Moon is 367 345 km (228 258 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 361 684 km (224 740 mi).
Moon after ascending node
1 day after ascending node on 25 August 2031 at 01:21 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 11 days, until the lunar orbit crosses from North to South in descending node on 6 September 2031 at 16:34 in ♉ Taurus.
Draconic month
1 day since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the beginning to the first part of the cycle.
Moon at southern standstill
At 23:55 the Moon is meeting its standstill point to reach South declination of ∠-20.731°. Over the next 13 days the lunar orbit is going to extend northward to face maximum declination of ∠20.623° at the point of next standstill in ♊ Gemini on 8 September 2031 at 23:27.
Syzygy in 5 days
In 5 days on 1 September 2031 at 09:20 in ♓ Pisces the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
