Moon phase and lunation details

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 11 February 2011 at 07:18.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon in ♊ Gemini

Moon is passing about ∠20° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1861"

Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1861" and ∠1943".

Snow Moon after 4 days

Next Full Moon is the Snow Moon of February 2011 after 4 days on 18 February 2011 at 08:36.

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 137 / 1090

The Moon is 9 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 137 of Meeus index or 1090 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.76 days

The length of the lunation is 29 days, 18 hours and 15 minutes. This is the year's longest synodic month of 2011. It is 29 minutes longer 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 5 hours and 31 minutes longer than the mean synodic month length. It is 1 hour and 32 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠139.2°

At the beginning of the lunation cycle the true anomaly is ∠139.2°. At the beginning of next synodic month the true anomaly is going to be ∠167°.

Moon before apogee

6 days after point of apogee on 6 February 2011 at 23:13 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 19 February 2011 at 07:27 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 385 197 km

The Moon is 385 197 km (239 350 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 358 247 km (222 604 mi).

Moon before descending node

13 days after ascending node on 30 January 2011 at 18:29 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 14 February 2011 at 08:14 in ♋ Cancer.

Draconic month

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

Moon at northern standstill

At 09:00 the Moon is meeting its standstill point to reach North declination of ∠24.080°. Over the next 12 days the lunar orbit is going to extend southward to face maximum declination of ∠-23.985° at the point of next standstill in ♐ Sagittarius on 25 February 2011 at 22:13.

Syzygy in 4 days

In 4 days on 18 February 2011 at 08:36 in ♌ Leo 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.
