Length of current 192 lunation is 29 days, 13 hours and 29 minutes. It is 2 hours and 19 minutes shorter than next lunation 193 length.

Lunation length longer than mean

Length of current synodic month is 45 minutes longer than the mean length of synodic month, but it is still 6 hours and 18 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠112.8°

This New Moon true anomaly is ∠112.8°. At beginning of next synodic month true anomaly will be ∠144.1°. 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

2 days after point of perigee on 2 August 2015 at 10:11 in ♓ Pisces. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 13 days, until it get to the point of next apogee on 18 August 2015 at 02:33 in ♎ Libra.
