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 ♊ Gemini

Moon is passing about ∠16° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1772"

Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1772" and ∠1905".

Harvest Moon after 21 days

Next Full Moon is the Harvest Moon of September 2012 after 21 days on 30 September 2012 at 03:19.

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 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 156 of Meeus index or 1109 from Brown series.

PreviousCurrent lunationNext

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 apogee

1 day after point of apogee on 7 September 2012 at 06:00 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 19 September 2012 at 02:52 in ♏ Scorpio.

Previous apogeeNext perigee

Distance to Moon 404 556 km

The Moon is 404 556 km (251 379 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 365 749 km (227 266 mi).

Moon after descending node

1 day after descending node on 7 September 2012 at 02:08 in ♉ Taurus. The Moon is located south of the ecliptic over the following 12 days, until the lunar orbit crosses from South to North in ascending node on 20 September 2012 at 12:54 in ♏ Scorpio.

Draconic month

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

Moon at northern standstill

At 18:10 the Moon is meeting its standstill point to reach North declination of ∠21.244°. Over the next 13 days the lunar orbit is going to extend southward to face maximum declination of ∠-21.135° at the point of next standstill in ♐ Sagittarius on 22 September 2012 at 00:11.

Syzygy in 7 days

In 7 days on 16 September 2012 at 02:11 in ♍ Virgo 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.
