Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon is entering ♐ Sagittarius

Moon is passing first ∠1° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1973"

Lunar disc appears visually 3.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1898".

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2012 after 7 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 156 / 1109

The Moon is 7 days young. Earth's natural satellite is moving through the first 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

Length of current 156 lunation is 29 days, 10 hours and 16 minutes. It is 24 minutes longer than next lunation 157 length.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 28 minutes shorter than the mean length of synodic month, but it is still 3 hours and 41 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠283.7°

This lunation true anomaly is ∠283.7°. At the beginning of next synodic month true anomaly will be ∠312.9°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon after perigee

1 day after point of perigee on 23 August 2012 at 19:39 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 13 days, until it get to the point of next apogee on 7 September 2012 at 06:00 in ♊ Gemini.

Distance to Moon 363 323 km

Moon is 363 323 km (225 758 mi) away from Earth on this date. Moon moves farther next 13 days until apogee, when Earth-Moon distance will reach 404 296 km (251 218 mi).

Moon in ascending node

Moon is in ascending node in ♐ Sagittarius at 11:38 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 13 days to meet descending node on 7 September 2012 at 02:08 in ♉ Taurus.

Previous nodeNext node

New draconic month

At 11:38 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon before southern standstill

12 days after previous North standstill on 12 August 2012 at 09:47 in ♊ Gemini, when Moon has reached northern declination of ∠21.492°. Next day the lunar orbit moves southward to face South declination of ∠-21.379° in the next southern standstill on 25 August 2012 at 18:40 in ♐ Sagittarius.

Syzygy in 7 days

After 7 days on 31 August 2012 at 13:58 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
