Lunar orbit position on

True anomaly ∠163.9°

This lunation true anomaly is ∠163.9°. At the beginning of next synodic month true anomaly will be ∠187.8°. 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

13 days after point of perigee on 21 September 2051 at 12:20 in ♈ Aries. 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 6 October 2051 at 15:34 in ♎ Libra.
