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 ♒ Aquarius

Moon is passing first ∠4° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1922"

Lunar disc appears visually 0.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1922" and ∠1929".

Hunter Moon after 7 days

Next Full Moon is the Hunter Moon of October 2012 after 7 days on 29 October 2012 at 19:50.

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 158 / 1111

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 158 of Meeus index or 1111 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.42 days

Length of current 158 lunation is 29 days, 10 hours and 5 minutes. It is 29 minutes shorter than next lunation 159 length.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 39 minutes shorter than the mean length of synodic month, but it is still 3 hours and 30 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠334.3°

This lunation true anomaly is ∠334.3°. At the beginning of next synodic month true anomaly will be ∠351.3°. 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

5 days after point of perigee on 17 October 2012 at 01:02 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 10 days, until it get to the point of next apogee on 1 November 2012 at 15:30 in ♊ Gemini.

Distance to Moon 372 918 km

Moon is 372 918 km (231 721 mi) away from Earth on this date. Moon moves farther next 10 days until apogee, when Earth-Moon distance will reach 406 050 km (252 308 mi).

Moon after ascending node

4 days after its ascending node on 17 October 2012 at 18:27 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 31 October 2012 at 10:36 in ♉ Taurus.

Draconic month

4 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.

Moon after southern standstill

3 days after previous South standstill on 19 October 2012 at 06:49 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.964°. Next 10 days the lunar orbit moves northward to face North declination of ∠20.920° in the next northern standstill on 2 November 2012 at 08:15 in ♊ Gemini.

Syzygy in 7 days

After 7 days on 29 October 2012 at 19:50 in ♉ Taurus, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
