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.

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 140 of Meeus index or 1093 from Brown series.

Synodic month length 29.59 days

Length of current 140 lunation is 29 days, 14 hours and 12 minutes. It is 2 hours and 21 minutes longer than next lunation 141 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 28 minutes longer than the mean length of synodic month, but it is still 5 hours and 35 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠216.7°

This lunation true anomaly is ∠216.7°. At the beginning of next synodic month true anomaly will be ∠248.4°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon before apogee

10 days after point of perigee on 15 May 2011 at 11:18 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 27 May 2011 at 09:58 in ♈ Aries.

Distance to Moon 403 283 km

Moon is 403 283 km (250 588 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 405 006 km (251 659 mi).

Moon after ascending node

6 days after its ascending node on 19 May 2011 at 09:03 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 2 June 2011 at 20:21 in ♊ Gemini.

Moon after southern standstill

6 days after previous South standstill on 18 May 2011 at 23:26 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.403°. Next 7 days the lunar orbit moves northward to face North declination of ∠23.393° in the next northern standstill on 2 June 2011 at 09:54 in ♊ Gemini.

Syzygy in 7 days

After 7 days on 1 June 2011 at 21:03 in ♊ Gemini, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
