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 ♓ Pisces

Moon is passing about ∠23° of ♓ Pisces tropical zodiac sector.

Apparent angular diameter ∠1786"

Lunar disc appears visually 8.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1786" and ∠1947".

Cold Moon after 7 days

Next Full Moon is the Cold Moon of December 2011 after 7 days on 10 December 2011 at 14:36.

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 147 / 1100

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 147 of Meeus index or 1100 from Brown series.

Synodic month length 29.5 days

The length of the lunation is 29 days, 11 hours and 57 minutes. It is 1 hour and 36 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 47 minutes shorter than the mean synodic month length. It is 5 hours and 22 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠21.6°

At the beginning of the lunation cycle the true anomaly is ∠21.6°. At the beginning of next synodic month the true anomaly is going to be ∠42.1°.

Moon before perigee

9 days after point of perigee on 23 November 2011 at 23:24 in ♏ Scorpio. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next apogee on 6 December 2011 at 01:13 in ♈ Aries.

Distance to Moon 401 334 km

The Moon is 401 334 km (249 377 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 405 414 km (251 913 mi).

Moon before descending node

7 days after ascending node on 26 November 2011 at 01:02 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following 6 days, until the lunar orbit crosses from North to South in descending node on 10 December 2011 at 07:04 in ♊ Gemini.

Draconic month

7 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

7 days since the previous standstill on 26 November 2011 at 06:47 in ♐ Sagittarius when the Moon has reached South declination of ∠-22.552°, the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠22.554° at the point of next northern standstill on 10 December 2011 at 13:37 in ♊ Gemini.

Syzygy in 7 days

In 7 days on 10 December 2011 at 14:36 in ♊ Gemini 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.
