Synodic month length 29.7 days

Length of current 345 lunation is 29 days, 16 hours and 48 minutes. It is 2 hours and 12 minutes shorter than next lunation 346 length.

Lunation length longer than mean

Length of current synodic month is 4 hours and 4 minutes longer than the mean length of synodic month, but it is still 2 hours and 59 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠96°

This New Moon true anomaly is ∠96°. At beginning of next synodic month true anomaly will be ∠132.4°. 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

1 day after point of perigee on 16 December 2027 at 02:21 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 14 days, until it get to the point of next apogee on 1 January 2028 at 03:52 in ♒ Aquarius.

Moon after northern standstill

3 days after previous North standstill on 13 December 2027 at 16:06 in ♊ Gemini, when Moon has reached northern declination of ∠26.569°. Next 9 days the lunar orbit moves southward to face South declination of ∠-26.576° in the next southern standstill on 26 December 2027 at 15:52 in ♐ Sagittarius.

Syzygy in 10 days

After 10 days on 27 December 2027 at 20:12 in ♐ Sagittarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
