Lunar orbit position on

True anomaly ∠263°

This lunation true anomaly is ∠263°. At the beginning of next synodic month true anomaly will be ∠296.1°. 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 perigee

13 days after point of apogee on 28 April 2019 at 18:20 in ♒ Aquarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 13 May 2019 at 21:53 in ♍ Virgo.
