Length of current 387 lunation is 29 days, 14 hours and 20 minutes. It is 47 minutes shorter than next lunation 388 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 36 minutes longer than the mean length of synodic month, but it is still 5 hours and 27 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠106.4°

This New Moon true anomaly is ∠106.4°. At beginning of next synodic month true anomaly will be ∠139.8°. 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 9 May 2031 at 07:28 in ♐ Sagittarius. 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 25 May 2031 at 02:08 in ♋ Cancer.

Moon after southern standstill

2 days after previous South standstill on 9 May 2031 at 07:56 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.092°. Next 11 days the lunar orbit moves northward to face North declination of ∠21.091° in the next northern standstill on 22 May 2031 at 19:41 in ♊ Gemini.
