Moon phase and lunation details

2 days after New Moon

Previous main lunar phase is the New Moon before 2 days on 16 September 2031 at 18:47.

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Moon in ♎ Libra

Moon is leaving the last ∠1° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.

Apparent angular diameter ∠1879"

Lunar disc appears visually 1.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1879" and ∠1910".

Harvest Moon after 11 days

Next Full Moon is the Harvest Moon of September 2031 after 11 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 392 / 1345

The Moon is 3 days young. Earth's natural satellite is moving from the beginning to the first 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 perigee

8 days after point of apogee on 11 September 2031 at 11:54 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 7 days, until it get to the point of next perigee on 27 September 2031 at 07:09 in ♒ Aquarius.

Previous apogeeNext perigee

Distance to Moon 381 512 km

Moon is 381 512 km (237 061 mi) away from Earth on this date. Moon moves closer next 7 days until perigee, when Earth-Moon distance will reach 366 841 km (227 944 mi).

Moon before ascending node

12 days after its descending node on 6 September 2031 at 16:34 in ♉ Taurus, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 21 September 2031 at 02:24 in ♏ Scorpio.

Draconic month

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

Moon before southern standstill

10 days after previous North standstill on 8 September 2031 at 23:27 in ♊ Gemini, when Moon has reached northern declination of ∠20.623°. Next 3 days the lunar orbit moves southward to face South declination of ∠-20.501° in the next southern standstill on 23 September 2031 at 05:46 in ♐ Sagittarius.

Syzygy in 11 days

After 11 days on 30 September 2031 at 18:58 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
