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

Length of current synodic month is 3 hours and 59 minutes shorter than the mean length of synodic month, but it is still 2 hours and 10 minutes longer, compared to 21st century shortest.

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 before perigee

11 days after point of apogee on 2 August 2017 at 17:55 in ♐ Sagittarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 18 August 2017 at 13:14 in ♋ Cancer.

Distance to Moon 366 811 km

Moon is 366 811 km (227 926 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 366 129 km (227 502 mi).

Moon after descending node

6 days after its descending node on 8 August 2017 at 10:56 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 6 days, until it will cross the ecliptic from South to North in ascending node on 21 August 2017 at 10:34 in ♌ Leo.

Moon before northern standstill

9 days after previous South standstill on 4 August 2017 at 18:17 in ♑ Capricorn, when Moon has reached southern declination of ∠-19.393°. Next 3 days the lunar orbit moves northward to face North declination of ∠19.381° in the next northern standstill on 18 August 2017 at 06:50 in ♋ Cancer.

Syzygy in 7 days

After 7 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.
