Lunation length shorter than mean

Length of current synodic month is 2 hours and 30 minutes shorter than the mean length of synodic month, but it is still 3 hours and 39 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠297.8°

This lunation true anomaly is ∠297.8°. At the beginning of next synodic month true anomaly will be ∠323.3°. 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

7 days after point of apogee on 26 September 2021 at 21:44 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 8 October 2021 at 17:28 in ♏ Scorpio.

Moon after northern standstill

5 days after previous North standstill on 29 September 2021 at 08:26 in ♋ Cancer, when Moon has reached northern declination of ∠26.109°. Next 7 days the lunar orbit moves southward to face South declination of ∠-26.204° in the next southern standstill on 12 October 2021 at 09:09 in ♑ Capricorn.
