Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 4 July 2031 at 19:01.

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 ♒ Aquarius

Moon is passing about ∠24° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1952"

Lunar disc appears visually 3.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1952" and ∠1887".

Buck Moon before 2 days

Next Full Moon is the Sturgeon Moon of August 2031 after 26 days on 3 August 2031 at 01:45.

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 389 / 1342

The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 389 of Meeus index or 1342 from Brown series.

Synodic month length 29.64 days

The length of the lunation is 29 days, 15 hours and 16 minutes. This is the year's longest synodic month of 2031. It is 24 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 2 hours and 31 minutes longer than the mean synodic month length. It is 4 hours and 31 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠165.9°

At the beginning of the lunation cycle the true anomaly is ∠165.9°. At the beginning of next synodic month the true anomaly is going to be ∠188.7°.

Moon after perigee

2 days after point of perigee on 4 July 2031 at 21:14 in ♑ Capricorn. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next apogee on 18 July 2031 at 14:28 in ♋ Cancer.

Distance to Moon 367 197 km

The Moon is 367 197 km (228 166 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 406 535 km (252 609 mi).

Moon after ascending node

5 days after ascending node on 1 July 2031 at 18:35 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 14 July 2031 at 12:38 in ♉ Taurus.

Draconic month

5 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the beginning to the first part of the cycle.

Moon after southern standstill

4 days since the previous standstill on 3 July 2031 at 05:15 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.077°, the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠21.045° at the point of next northern standstill on 16 July 2031 at 09:01 in ♊ Gemini.

Syzygy in 12 days

In 12 days on 19 July 2031 at 13:40 in ♋ Cancer 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.
