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 138 / 1091

The Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 138 of Meeus index or 1091 from Brown series.

Synodic month length 29.74 days

The length of the lunation is 29 days, 17 hours and 46 minutes. It is 1 hour and 28 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 5 hours and 2 minutes longer than the mean synodic month length. It is 2 hours and 1 minute shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠167°

At the beginning of the lunation cycle the true anomaly is ∠167°. At the beginning of next synodic month the true anomaly is going to be ∠190.9°.

Moon before perigee

11 days after point of perigee on 19 March 2011 at 19:09 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 day, until the Moon reaches the point of next apogee on 2 April 2011 at 09:00 in ♓ Pisces.

Distance to Moon 403 492 km

The Moon is 403 492 km (250 718 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 406 656 km (252 684 mi).

Moon after ascending node

5 days after ascending node on 25 March 2011 at 21:09 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following 9 days, until the lunar orbit crosses from North to South in descending node on 9 April 2011 at 12:48 in ♊ Gemini.

Moon after southern standstill

6 days since the previous standstill on 25 March 2011 at 05:02 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.716°, the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠23.569° at the point of next northern standstill on 8 April 2011 at 22:55 in ♊ Gemini.

Syzygy in 3 days

In 3 days on 3 April 2011 at 14:32 in ♈ Aries 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.
