Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 7 May 2031 at 03:40.

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 ♑ Capricorn

Moon is passing about ∠6° of ♑ Capricorn tropical zodiac sector.

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 387 / 1340

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 387 of Meeus index or 1340 from Brown series.

Synodic month length 29.6 days

The length of the lunation is 29 days, 14 hours and 20 minutes. It is 47 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 36 minutes longer than the mean synodic month length. It is 5 hours and 27 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠106.4°

At the beginning of the lunation cycle the true anomaly is ∠106.4°. At the beginning of next synodic month the true anomaly is going to be ∠139.8°.

Moon after perigee

1 day after point of perigee on 9 May 2031 at 07:28 in ♐ Sagittarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 14 days, until the Moon reaches the point of next apogee on 25 May 2031 at 02:08 in ♋ Cancer.

Distance to Moon 363 352 km

The Moon is 363 352 km (225 776 mi) away from Earth and getting further over the next 14 days until the point apogee when Earth-Moon distance is going to be 405 723 km (252 105 mi).

Moon after ascending node

2 days after ascending node on 7 May 2031 at 22:55 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 10 days, until the lunar orbit crosses from North to South in descending node on 21 May 2031 at 03:26 in ♉ Taurus.

Draconic month

2 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

1 day since the previous standstill on 9 May 2031 at 07:56 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.092°, the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠21.091° at the point of next northern standstill on 22 May 2031 at 19:41 in ♊ Gemini.

Syzygy in 10 days

In 10 days on 21 May 2031 at 07:17 in ♊ Gemini 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.
