Moon phase and lunation details

3 days after First Quarter

Previous main lunar phase is the First Quarter before 3 days on 25 August 2031 at 18:40.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon in ♑ Capricorn

Moon is leaving the last ∠4° of ♑ Capricorn tropical zodiac sector and will enter ♒ Aquarius later.

Lunar disc appears visually 3.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1900".

Harvest Moon after 2 days

Next Full Moon is the Harvest Moon of September 2031 after 2 days on 1 September 2031 at 09:20.

Upcoming main Moon phases

Lunation 391 / 1344

The Moon is 11 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 391 of Meeus index or 1344 from Brown series.

Synodic month length 29.59 days

Length of current 391 lunation is 29 days, 14 hours and 15 minutes. It is 41 minutes longer than next lunation 392 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 31 minutes longer than the mean length of synodic month, but it is still 5 hours and 32 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠213.5°

This lunation true anomaly is ∠213.5°. At the beginning of next synodic month true anomaly will be ∠245.2°. 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 perigee

14 days after point of apogee on 14 August 2031 at 21:37 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 30 August 2031 at 12:53 in ♒ Aquarius.

Previous apogeeNext perigee

Distance to Moon 363 374 km

Moon is 363 374 km (225 790 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 361 684 km (224 740 mi).

Moon after ascending node

4 days after its ascending node on 25 August 2031 at 01:21 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 6 September 2031 at 16:34 in ♉ Taurus.

Moon after southern standstill

2 days after previous South standstill on 26 August 2031 at 23:55 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.731°. Next 10 days the lunar orbit moves northward to face North declination of ∠20.623° in the next northern standstill on 8 September 2031 at 23:27 in ♊ Gemini.

Syzygy in 2 days

After 2 days on 1 September 2031 at 09:20 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
