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 is entering ♉ Taurus

Moon is passing first ∠4° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1774"

Lunar disc appears visually 6.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1774" and ∠1889".

Sturgeon Moon after 21 days

Next Full Moon is the Sturgeon Moon of August 2011 after 21 days on 13 August 2011 at 18:58.

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 142 / 1095

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 142 of Meeus index or 1095 from Brown series.

Synodic month length 29.41 days

The length of the lunation is 29 days, 9 hours and 46 minutes. It is 1 hour and 22 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 shorter than mean

The length of the current synodic month is 2 hours and 58 minutes shorter than the mean synodic month length. It is 3 hours and 11 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠283.1°

At the beginning of the lunation cycle the true anomaly is ∠283.1°. At the beginning of next synodic month the true anomaly is going to be ∠312.1°.

Moon after apogee

1 day after point of apogee on 21 July 2011 at 22:46 in ♈ Aries. 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 2 August 2011 at 20:59 in ♍ Virgo.

Distance to Moon 404 111 km

The Moon is 404 111 km (251 103 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 365 756 km (227 270 mi).

Moon before descending node

10 days after ascending node on 13 July 2011 at 02:27 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following 4 days, until the lunar orbit crosses from North to South in descending node on 27 July 2011 at 12:03 in ♊ Gemini.

Draconic month

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

Moon before northern standstill

10 days since the previous standstill on 12 July 2011 at 16:51 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.383°, the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠23.333° at the point of next northern standstill on 27 July 2011 at 03:02 in ♊ Gemini.

Syzygy in 7 days

In 7 days on 30 July 2011 at 18:40 in ♌ Leo 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.
