Moon phase and lunation details

5 days after New Moon

Previous main lunar phase is the New Moon before 5 days on 16 September 2012 at 02:11.

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Moon in ♐ Sagittarius

Moon is passing about ∠12° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1971"

Lunar disc appears visually 3.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1912".

Harvest Moon after 8 days

Next Full Moon is the Harvest Moon of September 2012 after 8 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 157 / 1110

The Moon is 6 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 157 of Meeus index or 1110 from Brown series.

Synodic month length 29.41 days

The length of the lunation is 29 days, 9 hours and 52 minutes. This is the year's shortest synodic month of 2012. It is 13 minutes shorter 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 52 minutes shorter than the mean synodic month length. It is 3 hours and 17 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠312.9°

At the beginning of the lunation cycle the true anomaly is ∠312.9°. At the beginning of next synodic month the true anomaly is going to be ∠334.3°.

Moon after perigee

2 days after point of perigee on 19 September 2012 at 02:52 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 13 days, until the Moon reaches the point of next apogee on 5 October 2012 at 00:43 in ♊ Gemini.

Previous perigeeNext apogee

Distance to Moon 363 614 km

The Moon is 363 614 km (225 939 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 405 162 km (251 756 mi).

Moon after ascending node

1 day after ascending node on 20 September 2012 at 12:54 in ♏ Scorpio. 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 4 October 2012 at 05:15 in ♉ Taurus.

Draconic month

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

Moon before southern standstill

12 days since the previous standstill on 8 September 2012 at 18:10 in ♊ Gemini when the Moon has reached North declination of ∠21.244°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-21.135° at the point of next southern standstill on 22 September 2012 at 00:11 in ♐ Sagittarius.

Syzygy in 8 days

In 8 days on 30 September 2012 at 03:19 in ♈ Aries 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.
