Lunar orbit position on

True anomaly ∠103.5°

This New Moon true anomaly is ∠103.5°. At beginning of next synodic month true anomaly will be ∠139.2°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after perigee

5 days after point of perigee on 22 January 2011 at 00:10 in ♍ Virgo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 10 days, until it get to the point of next apogee on 6 February 2011 at 23:13 in ♓ Pisces.
