Synodic month length 29.31 days

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

9 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 5 days, until it get to the point of next perigee on 16 September 2001 at 15:50 in ♍ Virgo.

Distance to Moon 374 215 km

Moon is 374 215 km (232 526 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 358 128 km (222 530 mi).

Moon before northern standstill

13 days after previous South standstill on 28 August 2001 at 23:14 in ♑ Capricorn, when Moon has reached southern declination of ∠-23.546°. Next day the lunar orbit moves northward to face North declination of ∠23.677° in the next northern standstill on 12 September 2001 at 12:19 in ♋ Cancer.

Syzygy in 5 days

After 5 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.
