Lunar orbit position on

True anomaly ∠319.9°

This lunation true anomaly is ∠319.9°. At the beginning of next synodic month true anomaly will be ∠339.4°. 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 apogee

4 days after point of apogee on 17 September 2038 at 19:15 in ♉ Taurus. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 7 days, until it get to the point of next perigee on 30 September 2038 at 00:20 in ♏ Scorpio.
