Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♊ Gemini

Moon is leaving the last ∠1° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Apparent angular diameter ∠1903"

Lunar disc appears visually 0.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1903" and ∠1916".

Hunter Moon after 22 days

Next Full Moon is the Hunter Moon of October 2010 after 22 days on 23 October 2010 at 01:36.

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 132 / 1085

The Moon is 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 132 of Meeus index or 1085 from Brown series.

Synodic month length 29.34 days

The length of the lunation is 29 days, 8 hours and 15 minutes. It is 1 hour and 52 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 4 hours and 29 minutes shorter than the mean synodic month length. It is 1 hour and 40 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠4.6°

At the beginning of the lunation cycle the true anomaly is ∠4.6°. At the beginning of next synodic month the true anomaly is going to be ∠20.4°.

Moon before apogee

9 days after point of apogee on 21 September 2010 at 08:03 in ♓ Pisces. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next perigee on 6 October 2010 at 13:41 in ♍ Virgo.

Distance to Moon 376 592 km

The Moon is 376 592 km (234 003 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 359 453 km (223 354 mi).

Moon before descending node

13 days after ascending node on 16 September 2010 at 13:56 in ♑ Capricorn. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 1 October 2010 at 02:42 in ♋ Cancer.

Draconic month

13 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the first to the middle part of the cycle.

Moon after northern standstill

1 day since the previous standstill on 29 September 2010 at 17:37 in ♊ Gemini when the Moon has reached North declination of ∠24.555°, the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-24.457° at the point of next southern standstill on 12 October 2010 at 07:49 in ♐ Sagittarius.

Syzygy in 7 days

In 7 days on 7 October 2010 at 18:44 in ♎ Libra 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.
