Sturgeon Moon after 17 days

Next Full Moon is the Sturgeon Moon of August 2031 after 17 days on 3 August 2031 at 01:45.

Upcoming main Moon phases

  • New Moon in Cancer ♋ on 19 July 2031 at 13:40
  • First Quarter in Scorpio ♏ on 27 July 2031 at 10:35

  • Last Quarter in Taurus ♉ on 10 August 2031 at 00:24

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 389 / 1342

The Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 389 of Meeus index or 1342 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.64 days

Length of current 389 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 next lunation 390 length.

Lunation length longer than mean

Length of current synodic month is 2 hours and 31 minutes longer than the mean length of synodic month, but it is still 4 hours and 31 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠165.9°

This lunation true anomaly is ∠165.9°. At the beginning of next synodic month true anomaly will be ∠188.7°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon before apogee

11 days after point of perigee on 4 July 2031 at 21:14 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 2 days, until it get to the point of next apogee on 18 July 2031 at 14:28 in ♋ Cancer.

Distance to Moon 403 239 km

Moon is 403 239 km (250 561 mi) away from Earth on this date. Moon moves farther next 2 days until apogee, when Earth-Moon distance will reach 406 535 km (252 609 mi).

Moon after descending node

1 day after its descending node on 14 July 2031 at 12:38 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 12 days, until it will cross the ecliptic from South to North in ascending node on 28 July 2031 at 23:54 in ♏ Scorpio.

Draconic month

14 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.

Moon in northern standstill

At 09:01 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠21.045°. Next 14 days the lunar orbit will move in opposite southward direction to face South declination of ∠-20.951° in its southern standstill point on 30 July 2031 at 15:45 in ♐ Sagittarius.

Syzygy in 3 days

After 3 days on 19 July 2031 at 13:40 in ♋ Cancer, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
