Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♉ Taurus

Moon is passing about ∠14° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1770"

Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1893".

Sturgeon Moon after 22 days

Next Full Moon is the Sturgeon Moon of August 2012 after 22 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 155 / 1108

The Moon is 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 155 of Meeus index or 1108 from Brown series.

Synodic month length 29.48 days

The length of the lunation is 29 days, 11 hours and 30 minutes. It is 1 hour and 14 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 1 hour and 14 minutes shorter than the mean synodic month length. It is 4 hours and 55 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠248.7°

At the beginning of the lunation cycle the true anomaly is ∠248.7°. At the beginning of next synodic month the true anomaly is going to be ∠283.7°.

Moon before perigee

11 days after point of perigee on 29 July 2012 at 08:30 in ♐ Sagittarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next day, until the Moon reaches the point of next apogee on 10 August 2012 at 10:51 in ♉ Taurus.

Distance to Moon 404 996 km

The Moon is 404 996 km (251 653 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 125 km (251 112 mi).

Moon before descending node

12 days after ascending node on 28 July 2012 at 10:34 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 11 August 2012 at 00:04 in ♊ Gemini.

Draconic month

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

Moon before northern standstill

10 days since the previous standstill on 29 July 2012 at 12:11 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.592°, the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠21.492° at the point of next northern standstill on 12 August 2012 at 09:47 in ♊ Gemini.

Syzygy in 8 days

In 8 days on 17 August 2012 at 15:54 in ♌ Leo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
