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 ♋ Cancer

Moon is passing about ∠21° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1904"

Lunar disc appears visually 0.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1904" and ∠1914".

Pink Moon after 6 days

Next Full Moon is the Pink Moon of April 2011 after 6 days on 18 April 2011 at 02:44.

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 139 / 1092

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 139 of Meeus index or 1092 from Brown series.

Synodic month length 29.68 days

The length of the lunation is 29 days, 16 hours and 18 minutes. It is 2 hours and 6 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 3 hours and 34 minutes longer than the mean synodic month length. It is 3 hours and 29 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠190.9°

At the beginning of the lunation cycle the true anomaly is ∠190.9°. At the beginning of next synodic month the true anomaly is going to be ∠216.7°.

Moon before apogee

9 days after point of apogee on 2 April 2011 at 09:00 in ♓ Pisces. 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 17 April 2011 at 05:59 in ♎ Libra.

Previous apogeeNext perigee

Distance to Moon 376 482 km

The Moon is 376 482 km (233 935 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 358 088 km (222 506 mi).

Moon after descending node

1 day after descending node on 9 April 2011 at 12:48 in ♊ Gemini. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 22 April 2011 at 01:05 in ♐ Sagittarius.

Previous nodeNext node

Draconic month

16 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the second to the final part of the cycle.

Moon after northern standstill

2 days since the previous standstill on 8 April 2011 at 22:55 in ♊ Gemini when the Moon has reached North declination of ∠23.569°, the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-23.498° at the point of next southern standstill on 21 April 2011 at 13:40 in ♐ Sagittarius.

Syzygy in 6 days

In 6 days on 18 April 2011 at 02:44 in ♎ Libra 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.
