Lunar orbit position on

True anomaly ∠139.2°

This New Moon true anomaly is ∠139.2°. At beginning of next synodic month true anomaly will be ∠167°. 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
