Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day 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 in ♊ Gemini

Moon is passing about ∠8° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1770"

Lunar disc appears visually 6.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1894".

Sturgeon Moon after 20 days

Next Full Moon is the Sturgeon Moon of August 2012 after 20 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 23 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.

PreviousCurrent lunationNext

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

1 day 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 12 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 405 008 km

The Moon is 405 008 km (251 660 mi) away from Earth and getting closer over the next 12 days until the point perigee when Earth-Moon distance is going to be 369 731 km (229 740 mi).

Moon in descending node

Moon is in descending node in ♊ Gemini at 00:04 crossing the ecliptic from North to South to meet ascending node 12 days later on 24 August 2012 at 11:38 in ♐ Sagittarius.

Draconic month

14 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 before northern standstill

12 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 day 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 6 days

In 6 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.
