Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 30 September 2031 at 18:58.

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 ♊ Gemini

Moon is passing about ∠22° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1785"

Lunar disc appears visually 7.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1785" and ∠1920".

Harvest Moon before 5 days

Next Full Moon is the Hunter Moon of October 2031 after 23 days on 30 October 2031 at 07:33.

Upcoming main Moon phases

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 392 / 1345

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 392 of Meeus index or 1345 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.57 days

Length of current 392 lunation is 29 days, 13 hours and 34 minutes. It is 45 minutes longer than next lunation 393 length.

Lunation length longer than mean

Length of current synodic month is 50 minutes longer than the mean length of synodic month, but it is still 6 hours and 13 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠245.2°

This lunation true anomaly is ∠245.2°. At the beginning of next synodic month true anomaly will be ∠281.8°. 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

9 days after point of perigee on 27 September 2031 at 07:09 in ♒ Aquarius. 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 9 October 2031 at 06:23 in ♋ Cancer.

Previous perigeeNext apogee

Distance to Moon 401 532 km

Moon is 401 532 km (249 500 mi) away from Earth on this date. Moon moves farther next 2 days until apogee, when Earth-Moon distance will reach 404 365 km (251 261 mi).

Moon after descending node

2 days after its descending node on 3 October 2031 at 22:04 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 11 days, until it will cross the ecliptic from South to North in ascending node on 18 October 2031 at 06:54 in ♏ Scorpio.

Draconic month

15 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 07:31 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠20.418°. Next 13 days the lunar orbit will move in opposite southward direction to face South declination of ∠-20.359° in its southern standstill point on 20 October 2031 at 11:06 in ♐ Sagittarius.

Syzygy in 9 days

After 9 days on 16 October 2031 at 08:21 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
