Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 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 ♐ Sagittarius

Moon is passing about ∠21° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1968"

Lunar disc appears visually 3.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1968" and ∠1900".

Flower Moon before 2 days

Next Full Moon is the Strawberry Moon of June 2031 after 26 days on 5 June 2031 at 11:58.

Upcoming main Moon phases

  • Last Quarter in Aquarius ♒ on 13 May 2031 at 19:07
  • New Moon in Gemini ♊ on 21 May 2031 at 07:17
  • First Quarter in Virgo ♍ on 29 May 2031 at 11:20
  • Full Moon in Sagittarius ♐ on 5 June 2031 at 11:58

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 17 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.

PreviousCurrent lunationNext

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 at perigee

Moon is at perigee at 07:28. It is 11 days after previous apogee on 27 April 2031 at 10:30 in ♋ Cancer. Lunar orbit is going to widen while the Moon is moving away from the Earth over the next 15 days, until point of next apogee on 25 May 2031 at 02:08 in ♋ Cancer.

Previous apogeeNext apogee

Distance to Moon 362 851 km

This perigee Moon is 362 851 km (225 465 mi) away from Earth. It is 343 km closer than the mean perigee distance, but it is still 7 505 km further than the closest perigee of 21st century.

Moon after ascending node

1 day after ascending node on 7 May 2031 at 22:55 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 21 May 2031 at 03:26 in ♉ Taurus.

Previous nodeNext node

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 07:56 the Moon is meeting its standstill point to reach South declination of ∠-21.092°. Over the next 13 days the lunar orbit is going to extend northward to face maximum declination of ∠21.091° at the point of next standstill in ♊ Gemini on 22 May 2031 at 19:41.

Previous standstillNext standstill

Syzygy in 11 days

In 11 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.
