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 ♈ Aries

Moon is passing about ∠14° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1896"

Lunar disc appears visually 2.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1896" and ∠1951".

Wolf Moon after 6 days

Next Full Moon is the Wolf Moon of January 2009 after 6 days on 11 January 2009 at 03:27.

Upcoming main Moon phases

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 111 / 1064

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 111 of Meeus index or 1064 from Brown series.

Synodic month length 29.81 days

The length of the lunation is 29 days, 19 hours and 33 minutes. This is the year's longest synodic month of 2009. It is 1 hour and 53 minutes longer 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 longer than mean

The length of the current synodic month is 6 hours and 49 minutes longer than the mean synodic month length. It is 14 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠186.6°

At the beginning of the lunation cycle the true anomaly is ∠186.6°. At the beginning of next synodic month the true anomaly is going to be ∠213.2°.

Moon before apogee

8 days after point of apogee on 26 December 2008 at 17:50 in ♐ Sagittarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next perigee on 10 January 2009 at 10:52 in ♋ Cancer.

Previous apogeeNext perigee

Distance to Moon 377 983 km

The Moon is 377 983 km (234 868 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 357 501 km (222 141 mi).

Moon after ascending node

5 days after ascending node on 30 December 2008 at 07:40 in ♒ Aquarius. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 12 January 2009 at 08:34 in ♌ Leo.

Draconic month

5 days since the beginning of current draconic month in ♒ Aquarius, the Moon is navigating from the beginning to the first part of the cycle.

Moon before northern standstill

9 days since the previous standstill on 26 December 2008 at 08:03 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.026°, the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠27.060° at the point of next northern standstill on 9 January 2009 at 05:38 in ♊ Gemini.

Syzygy in 6 days

In 6 days on 11 January 2009 at 03:27 in ♋ Cancer 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.
