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 ♐ Sagittarius

Moon is passing about ∠19° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1946"

Lunar disc appears visually 2.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1946" and ∠1904".

Harvest Moon after 7 days

Next Full Moon is the Harvest Moon of September 2038 after 7 days on 13 September 2038 at 12:24.

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 478 / 1431

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 478 of Meeus index or 1431 from Brown series.

Synodic month length 29.36 days

Length of current 478 lunation is 29 days, 8 hours and 45 minutes. This is the year's shortest synodic month of 2038. It is 10 minutes shorter than next lunation 479 length.

Lunation length shorter than mean

Length of current synodic month is 3 hours and 59 minutes shorter than the mean length of synodic month, but it is still 2 hours and 10 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠319.9°

This lunation true anomaly is ∠319.9°. At the beginning of next synodic month true anomaly will be ∠339.4°. 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

4 days after point of perigee on 1 September 2038 at 22:39 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 11 days, until it get to the point of next apogee on 17 September 2038 at 19:15 in ♉ Taurus.

Distance to Moon 368 295 km

Moon is 368 295 km (228 848 mi) away from Earth on this date. Moon moves farther next 11 days until apogee, when Earth-Moon distance will reach 405 516 km (251 976 mi).

Moon before descending node

11 days after its ascending node on 26 August 2038 at 03:40 in ♋ Cancer, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 7 September 2038 at 20:51 in ♑ Capricorn.

Moon before southern standstill

11 days after previous North standstill on 26 August 2038 at 08:58 in ♋ Cancer, when Moon has reached northern declination of ∠23.151°. Next day the lunar orbit moves southward to face South declination of ∠-23.232° in the next southern standstill on 8 September 2038 at 03:20 in ♑ Capricorn.

Syzygy in 7 days

After 7 days on 13 September 2038 at 12:24 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
