Lunation length shorter than mean

Length of current synodic month is 48 minutes shorter than the mean length of synodic month, but it is still 5 hours and 21 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠312.6°

This lunation true anomaly is ∠312.6°. At the beginning of next synodic month true anomaly will be ∠334.7°. 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 before perigee

8 days after point of apogee on 3 December 2031 at 22:35 in ♌ Leo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 3 days, until it get to the point of next perigee on 15 December 2031 at 21:31 in ♑ Capricorn.

Moon before southern standstill

12 days after previous North standstill on 30 November 2031 at 00:08 in ♊ Gemini, when Moon has reached northern declination of ∠20.350°. Next day the lunar orbit moves southward to face South declination of ∠-20.356° in the next southern standstill on 14 December 2031 at 04:45 in ♐ Sagittarius.
