Length of current 20 lunation is 29 days, 7 hours and 32 minutes. It is 1 hour and 24 minutes shorter than next lunation 21 length.

Lunation length shorter than mean

Length of current synodic month is 5 hours and 12 minutes shorter than the mean length of synodic month, but it is still 57 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠358.1°

This New Moon true anomaly is ∠358.1°. At beginning of next synodic month true anomaly will be ∠13.2°. 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

11 days after point of apogee on 1 September 2001 at 23:26 in ♒ Aquarius. 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 16 September 2001 at 15:50 in ♍ Virgo.

1 day after its ascending node on 11 September 2001 at 21:36 in ♊ Gemini, the Moon is following the northern part of its orbit for the next 10 days, until it will cross the ecliptic from North to South in descending node on 24 September 2001 at 10:28 in ♑ Capricorn.

Moon after northern standstill

1 day after previous North standstill on 12 September 2001 at 12:19 in ♋ Cancer, when Moon has reached northern declination of ∠23.677°. Next 11 days the lunar orbit moves southward to face South declination of ∠-23.780° in the next southern standstill on 25 September 2001 at 05:14 in ♑ Capricorn.

Syzygy in 3 days

After 3 days on 17 September 2001 at 10:27 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
