Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 26 January 2011 at 12:57.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Synodic month length 29.73 days

The length of the lunation is 29 days, 17 hours and 28 minutes. It is 47 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 4 hours and 44 minutes longer than the mean synodic month length. It is 2 hours and 19 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠103.5°

At the beginning of the lunation cycle the true anomaly is ∠103.5°. At the beginning of next synodic month the true anomaly is going to be ∠139.2°.

Moon after perigee

5 days after point of perigee on 22 January 2011 at 00:10 in ♍ Virgo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next apogee on 6 February 2011 at 23:13 in ♓ Pisces.

Distance to Moon 371 591 km

The Moon is 371 591 km (230 896 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 924 km (252 229 mi).

Moon before ascending node

9 days after descending node on 18 January 2011 at 00:06 in ♋ Cancer. The Moon is located south of the ecliptic over the following 3 days, until the lunar orbit crosses from South to North in ascending node on 30 January 2011 at 18:29 in ♐ Sagittarius.

Moon before southern standstill

10 days since the previous standstill on 16 January 2011 at 22:51 in ♊ Gemini when the Moon has reached North declination of ∠24.221°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-24.180° at the point of next southern standstill on 29 January 2011 at 16:26 in ♐ Sagittarius.

Syzygy in 6 days

In 6 days on 3 February 2011 at 02:31 in ♒ Aquarius 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.
