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 in perigee

Moon is reaching point of perigee on this date at 05:59, this is 14 days after last apogee on 2 April 2011 at 09:00 in ♓ Pisces. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 12 days ahead, until it will get to the point of next apogee on 29 April 2011 at 18:02 in ♓ Pisces.
