Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon in ♏ Scorpio

Moon is passing about ∠5° of ♏ Scorpio tropical zodiac sector.

Apparent angular diameter ∠1901"

Lunar disc appears visually 0.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1901" and ∠1889".

Sturgeon Moon after 6 days

Next Full Moon is the Sturgeon Moon of August 2031 after 6 days on 3 August 2031 at 01:45.

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.

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 390 of Meeus index or 1343 from Brown series.

Synodic month length 29.62 days

Length of current 390 lunation is 29 days, 14 hours and 52 minutes. It is 37 minutes longer than next lunation 391 length.

Lunation length longer than mean

Length of current synodic month is 2 hours and 8 minutes longer than the mean length of synodic month, but it is still 4 hours and 55 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠188.7°

This lunation true anomaly is ∠188.7°. At the beginning of next synodic month true anomaly will be ∠213.5°. 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 18 July 2031 at 14:28 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 2 August 2031 at 06:47 in ♑ Capricorn.

Distance to Moon 377 019 km

Moon is 377 019 km (234 269 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 358 060 km (222 488 mi).

Moon before ascending node

12 days after its descending node on 14 July 2031 at 12:38 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 28 July 2031 at 23:54 in ♏ Scorpio.

Moon before southern standstill

11 days after previous North standstill on 16 July 2031 at 09:01 in ♊ Gemini, when Moon has reached northern declination of ∠21.045°. Next 3 days the lunar orbit moves southward to face South declination of ∠-20.951° in the next southern standstill on 30 July 2031 at 15:45 in ♐ Sagittarius.

Syzygy in 6 days

After 6 days on 3 August 2031 at 01:45 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
