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 after perigee

2 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 9 days, until it get to the point of next apogee on 27 May 2011 at 09:58 in ♈ Aries.

Moon before southern standstill

11 days after previous North standstill on 6 May 2011 at 03:54 in ♊ Gemini, when Moon has reached northern declination of ∠23.421°. Next day the lunar orbit moves southward to face South declination of ∠-23.403° in the next southern standstill on 18 May 2011 at 23:26 in ♐ Sagittarius.
