Moon phase and lunation details

Moonrise and moonset

Moon rises at sunrise and sets at sunset. It's part facing the Earth is completely in shadow.

Moon in ♍ Virgo

Moon is passing about ∠20° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter

Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1814" and ∠1909".

Harvest Moon after 14 days

Next Full Moon is the Harvest Moon of September 2031 after 14 days on 30 September 2031 at 18:58.

Upcoming main Moon phases

Spring tide

There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.

New lunation 392 / 1345

At 18:47 on this date the Moon completes the old and enters a new synodic month with lunation 392 of Meeus index or 1345 from Brown series.


Synodic month length 29.57 days

29 days, 13 hours and 34 minutes is the length of new lunation 392. 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 after apogee

5 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 10 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 395 154 km

Moon is 395 154 km (245 537 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 366 841 km (227 944 mi).

Moon before ascending node

9 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 4 days, until it will cross the ecliptic from South to North in ascending node on 21 September 2031 at 02:24 in ♏ Scorpio.

Draconic month

22 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

7 days after previous North standstill on 8 September 2031 at 23:27 in ♊ Gemini, when Moon has reached northern declination of ∠20.623°. Next 6 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.
