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 ∠16° of ♏ Scorpio tropical zodiac sector.

Apparent angular diameter ∠1972"

Lunar disc appears visually 4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1894".

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2100 after 7 days on 19 August 2100 at 21:29.

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 1244 / 2197

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 1244 of Meeus index or 2197 from Brown series.

Synodic month length 29.41 days

The length of the lunation is 29 days, 9 hours and 48 minutes. It is 35 minutes longer 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 2 hours and 56 minutes shorter than the mean synodic month length. It is 3 hours and 13 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠294.6°

At the beginning of the lunation cycle the true anomaly is ∠294.6°. At the beginning of next synodic month the true anomaly is going to be ∠320.8°.

Moon after perigee

1 day after point of perigee on 10 August 2100 at 16:07 in ♎ Libra. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 13 days, until the Moon reaches the point of next apogee on 25 August 2100 at 23:00 in ♉ Taurus.

Distance to Moon 363 526 km

The Moon is 363 526 km (225 885 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 404 637 km (251 430 mi).

Moon after descending node

4 days after descending node on 7 August 2100 at 17:51 in ♍ Virgo. The Moon is located south of the ecliptic over the following 8 days, until the lunar orbit crosses from South to North in ascending node on 20 August 2100 at 18:39 in ♓ Pisces.

Draconic month

19 days since the beginning of current draconic month in ♓ Pisces, the Moon is navigating from the second to the final part of the cycle.

Moon before southern standstill

10 days since the previous standstill on 2 August 2100 at 09:03 in ♊ Gemini when the Moon has reached North declination of ∠28.293°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-28.334° at the point of next southern standstill on 15 August 2100 at 09:13 in ♐ Sagittarius.

Syzygy in 7 days

In 7 days on 19 August 2100 at 21:29 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.
