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 is entering ♐ Sagittarius

Moon is passing first ∠2° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1910"

Lunar disc appears visually 0.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1910" and ∠1896".

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2037 after 7 days on 25 August 2037 at 19:09.

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 465 / 1418

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 465 of Meeus index or 1418 from Brown series.

Synodic month length 29.32 days

The length of the lunation is 29 days, 7 hours and 44 minutes. This is the year's shortest synodic month of 2037. It is 25 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 5 hours shorter than the mean synodic month length. It is 1 hour and 9 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠338.4°

At the beginning of the lunation cycle the true anomaly is ∠338.4°. At the beginning of next synodic month the true anomaly is going to be ∠354.5°.

Moon after perigee

5 days after point of perigee on 12 August 2037 at 17:37 in ♍ Virgo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next apogee on 28 August 2037 at 00:28 in ♈ Aries.

Distance to Moon 375 284 km

The Moon is 375 284 km (233 191 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 214 km (252 410 mi).

Moon before descending node

8 days after ascending node on 10 August 2037 at 01:40 in ♋ Cancer. The Moon is located north of the ecliptic over the following 4 days, until the lunar orbit crosses from North to South in descending node on 22 August 2037 at 23:10 in ♑ Capricorn.

Draconic month

8 days since the beginning of current draconic month in ♋ Cancer, the Moon is navigating from the beginning to the first part of the cycle.

Moon before southern standstill

9 days since the previous standstill on 8 August 2037 at 21:01 in ♋ Cancer when the Moon has reached North declination of ∠21.369°, the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-21.390° at the point of next southern standstill on 21 August 2037 at 14:16 in ♑ Capricorn.

Syzygy in 7 days

In 7 days on 25 August 2037 at 19:09 in ♒ Aquarius the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
