Moon phase and lunation details

2 days after Last Quarter

Previous main lunar phase is the Last Quarter before 2 days on 8 September 2031 at 16:14.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♋ Cancer

Moon is passing about ∠19° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 7.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1906".

Harvest Moon after 19 days

Next Full Moon is the Harvest Moon of September 2031 after 19 days on 30 September 2031 at 18:58.

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 391 / 1344

The Moon is 24 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 391 of Meeus index or 1344 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.59 days

The length of the lunation is 29 days, 14 hours and 15 minutes. It is 41 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 1 hour and 31 minutes longer than the mean synodic month length. It is 5 hours and 32 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠213.5°

At the beginning of the lunation cycle the true anomaly is ∠213.5°. At the beginning of next synodic month the true anomaly is going to be ∠245.2°.

Moon at apogee

Moon is at apogee at 11:54. It is 11 days after previous perigee on 30 August 2031 at 12:53 in ♒ Aquarius. Lunar orbit is going to narrow while the Moon is moving towards the Earth over the next 15 days, until point of next perigee on 27 September 2031 at 07:09 in ♒ Aquarius.

Previous perigeeNext perigee

Distance to Moon 405 006 km

This apogee Moon is 405 006 km (251 659 mi) away from Earth. It is 402 km further than the mean apogee distance, but it is still 1 703 km closer than the farthest apogee of 21st century.

Moon after descending node

4 days after descending node on 6 September 2031 at 16:34 in ♉ Taurus. The Moon is located south of the ecliptic over the following 9 days, until the lunar orbit crosses from South to North in ascending node on 21 September 2031 at 02:24 in ♏ Scorpio.

Draconic month

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

Moon after northern standstill

2 days since the previous standstill on 8 September 2031 at 23:27 in ♊ Gemini when the Moon has reached North declination of ∠20.623°, the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-20.501° at the point of next southern standstill on 23 September 2031 at 05:46 in ♐ Sagittarius.

Previous standstillNext standstill

Syzygy in 5 days

In 5 days on 16 September 2031 at 18:47 in ♍ Virgo 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.
