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 ∠15° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1968"

Lunar disc appears visually 3.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1968" and ∠1899".

Sturgeon Moon after 6 days

Next Full Moon is the Sturgeon Moon of August 2012 after 6 days on 31 August 2012 at 13:58.

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 156 / 1109

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 156 of Meeus index or 1109 from Brown series.

Synodic month length 29.43 days

The length of the lunation is 29 days, 10 hours and 16 minutes. It is 24 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 28 minutes shorter than the mean synodic month length. It is 3 hours and 41 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠283.7°

At the beginning of the lunation cycle the true anomaly is ∠283.7°. At the beginning of next synodic month the true anomaly is going to be ∠312.9°.

Moon after perigee

1 day after point of perigee on 23 August 2012 at 19:39 in ♏ Scorpio. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 12 days, until the Moon reaches the point of next apogee on 7 September 2012 at 06:00 in ♊ Gemini.

Distance to Moon 364 146 km

The Moon is 364 146 km (226 270 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 404 296 km (251 218 mi).

Moon after ascending node

1 day after ascending node on 24 August 2012 at 11:38 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following 12 days, until the lunar orbit crosses from North to South in descending node on 7 September 2012 at 02:08 in ♉ Taurus.

Draconic month

1 day since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the beginning to the first part of the cycle.

Moon at southern standstill

At 18:40 the Moon is meeting its standstill point to reach South declination of ∠-21.379°. Over the next 14 days the lunar orbit is going to extend northward to face maximum declination of ∠21.244° at the point of next standstill in ♊ Gemini on 8 September 2012 at 18:10.

Syzygy in 6 days

In 6 days on 31 August 2012 at 13:58 in ♓ Pisces 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.
