Synodic month length 29.49 days

Length of current 914 lunation is 29 days, 11 hours and 43 minutes. It is 1 hour and 59 minutes shorter than next lunation 915 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 1 minute shorter than the mean length of synodic month, but it is still 5 hours and 8 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠22.5°

This New Moon true anomaly is ∠22.5°. At beginning of next synodic month true anomaly will be ∠43.1°. 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 before perigee

8 days after point of apogee on 9 December 2073 at 22:16 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 7 days, until it get to the point of next perigee on 25 December 2073 at 23:45 in ♏ Scorpio.

Moon after northern standstill

2 days after previous North standstill on 15 December 2073 at 22:12 in ♋ Cancer, when Moon has reached northern declination of ∠20.261°. Next 10 days the lunar orbit moves southward to face South declination of ∠-20.262° in the next southern standstill on 28 December 2073 at 21:38 in ♑ Capricorn.

Syzygy in 10 days

After 10 days on 28 December 2073 at 16:55 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
