Synodic month length 29.36 days

Length of current 217 lunation is 29 days, 8 hours and 45 minutes. It is 2 hours and 15 minutes shorter than next lunation 218 length.

Lunation length shorter than mean

Lunar orbit position on

True anomaly ∠27.9°

This New Moon true anomaly is ∠27.9°. At beginning of next synodic month true anomaly will be ∠49.5°. 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 in perigee

Moon is reaching point of perigee on this date at 13:14, this is 15 days after last apogee on 2 August 2017 at 17:55 in ♐ Sagittarius.

Distance to Moon 366 129 km

This perigee Moon is 366 129 km (227 502 mi) away from Earth. It is 3 621 km closer than the mean perigee distance, but it is still 4 227 km farther than the closest perigee of 21st century.

Moon in northern standstill

At 06:50 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠19.381°. Next 13 days the lunar orbit will move in opposite southward direction to face South declination of ∠-19.393° in its southern standstill point on 1 September 2017 at 02:03 in ♑ Capricorn.

Syzygy in 3 days

After 3 days on 21 August 2017 at 18:30 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
