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 141 / 1094

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 141 of Meeus index or 1094 from Brown series.

Synodic month length 29.49 days

The length of the lunation is 29 days, 11 hours and 51 minutes. It is 2 hours and 5 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 53 minutes shorter than the mean synodic month length. It is 5 hours and 16 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠248.4°

At the beginning of the lunation cycle the true anomaly is ∠248.4°. At the beginning of next synodic month the true anomaly is going to be ∠283.1°.

Moon before perigee

11 days after point of perigee on 12 June 2011 at 01:42 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 day, until the Moon reaches the point of next apogee on 24 June 2011 at 04:13 in ♈ Aries.

Distance to Moon 405 243 km

The Moon is 405 243 km (251 806 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 275 km (251 205 mi).

Moon before descending node

7 days after ascending node on 15 June 2011 at 18:35 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 30 June 2011 at 04:14 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

8 days since the previous standstill on 15 June 2011 at 08:52 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.399°, the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠23.399° at the point of next northern standstill on 29 June 2011 at 17:46 in ♊ Gemini.

Syzygy in 7 days

In 7 days on 1 July 2011 at 08:54 in ♋ Cancer 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.
