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 in ♒ Aquarius

Moon is passing about ∠20° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1773"

Lunar disc appears visually 8.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1773" and ∠1931".

Beaver Moon after 6 days

Next Full Moon is the Beaver Moon of November 2009 after 6 days on 2 November 2009 at 19:14.

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 121 / 1074

The Moon is 9 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 121 of Meeus index or 1074 from Brown series.

Synodic month length 29.57 days

The length of the lunation is 29 days, 13 hours and 41 minutes. It is 3 hours and 7 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 longer than mean

The length of the current synodic month is 57 minutes longer than the mean synodic month length. It is 6 hours and 6 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠65.2°

At the beginning of the lunation cycle the true anomaly is ∠65.2°. At the beginning of next synodic month the true anomaly is going to be ∠99.9°.

Moon after apogee

1 day after point of apogee on 25 October 2009 at 23:18 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 7 November 2009 at 07:30 in ♋ Cancer.

Distance to Moon 404 378 km

The Moon is 404 378 km (251 269 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 368 900 km (229 224 mi).

Moon after ascending node

2 days after ascending node on 25 October 2009 at 08:52 in ♑ Capricorn. The Moon is located north of the ecliptic over the following 11 days, until the lunar orbit crosses from North to South in descending node on 7 November 2009 at 23:25 in ♋ Cancer.

Draconic month

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

Moon after southern standstill

4 days since the previous standstill on 22 October 2009 at 12:10 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.951°, the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠25.856° at the point of next northern standstill on 5 November 2009 at 15:31 in ♊ Gemini.

Syzygy in 6 days

In 6 days on 2 November 2009 at 19:14 in ♉ Taurus 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.
