Moon phase and lunation details

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 9 August 2012 at 18:55.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon is entering ♋ Cancer

Moon is passing first ∠2° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1787"

Lunar disc appears visually 5.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1787" and ∠1894".

Sturgeon Moon after 18 days

Next Full Moon is the Sturgeon Moon of August 2012 after 18 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 25 days old. Earth's natural satellite is moving from the second to the final 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 after apogee

3 days after point of apogee on 10 August 2012 at 10:51 in ♉ Taurus. 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 23 August 2012 at 19:39 in ♏ Scorpio.

Previous apogeeNext perigee

Distance to Moon 401 115 km

The Moon is 401 115 km (249 241 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 369 731 km (229 740 mi).

Moon after descending node

2 days after descending node on 11 August 2012 at 00:04 in ♊ Gemini. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 24 August 2012 at 11:38 in ♐ Sagittarius.

Draconic month

16 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 after northern standstill

1 day since the previous standstill on 12 August 2012 at 09:47 in ♊ Gemini when the Moon has reached North declination of ∠21.492°, the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-21.379° at the point of next southern standstill on 25 August 2012 at 18:40 in ♐ Sagittarius.

Syzygy in 4 days

In 4 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.
