Moonrise and moonset

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

Moon is passing about ∠16° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1967"

Lunar disc appears visually 1.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1967" and ∠1929".

Hunter Moon after 5 days

Next Full Moon is the Hunter Moon of October 2031 after 5 days on 30 October 2031 at 07:33.

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 9 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 393 of Meeus index or 1346 from Brown series.

Synodic month length 29.53 days

Length of current 393 lunation is 29 days, 12 hours and 49 minutes. It is 53 minutes longer than next lunation 394 length.

Lunation length longer than mean

Length of current synodic month is 5 minutes longer than the mean length of synodic month, but it is still 6 hours and 58 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠281.8°

This lunation true anomaly is ∠281.8°. At the beginning of next synodic month true anomaly will be ∠312.6°. 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 perigee

1 day after point of perigee on 22 October 2031 at 20:06 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 12 days, until it get to the point of next apogee on 6 November 2031 at 02:45 in ♌ Leo.

Distance to Moon 364 360 km

Moon is 364 360 km (226 403 mi) away from Earth on this date. Moon moves farther next 12 days until apogee, when Earth-Moon distance will reach 404 522 km (251 358 mi).

Moon after ascending node

6 days after its ascending node on 18 October 2031 at 06:54 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 6 days, until it will cross the ecliptic from North to South in descending node on 31 October 2031 at 06:09 in ♉ Taurus.

Moon after southern standstill

4 days after previous South standstill on 20 October 2031 at 11:06 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.359°. Next 9 days the lunar orbit moves northward to face North declination of ∠20.333° in the next northern standstill on 2 November 2031 at 15:55 in ♊ Gemini.

Syzygy in 5 days

After 5 days on 30 October 2031 at 07:33 in ♉ Taurus, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
