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 139 / 1092

The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 139 of Meeus index or 1092 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.68 days

Length of current 139 lunation is 29 days, 16 hours and 18 minutes. It is 2 hours and 6 minutes longer than next lunation 140 length.

Lunation length longer than mean

Length of current synodic month is 3 hours and 34 minutes longer than the mean length of synodic month, but it is still 3 hours and 29 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠190.9°

This lunation true anomaly is ∠190.9°. At the beginning of next synodic month true anomaly will be ∠216.7°. 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 after perigee

5 days after point of perigee on 17 April 2011 at 05:59 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 7 days, until it get to the point of next apogee on 29 April 2011 at 18:02 in ♓ Pisces.

Moon after southern standstill

1 day after previous South standstill on 21 April 2011 at 13:40 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.498°. Next 13 days the lunar orbit moves northward to face North declination of ∠23.421° in the next northern standstill on 6 May 2011 at 03:54 in ♊ Gemini.
