Moon phase and lunation details

6 days after First Quarter

Synodic month length 29.46 days

Length of current 218 lunation is 29 days, 11 hours and 1 minute. It is 2 hours and 42 minutes shorter than next lunation 219 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 44 minutes shorter than the mean length of synodic month, but it is still 4 hours and 25 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠49.5°

This New Moon true anomaly is ∠49.5°. At beginning of next synodic month true anomaly will be ∠79°. 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 after apogee

5 days after point of apogee on 30 August 2017 at 11:25 in ♐ Sagittarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 9 days, until it get to the point of next perigee on 13 September 2017 at 16:04 in ♊ Gemini.

Distance to Moon 394 515 km

Moon is 394 515 km (245 140 mi) away from Earth on this date. Moon moves closer next 9 days until perigee, when Earth-Moon distance will reach 369 856 km (229 818 mi).

Moon after southern standstill

3 days after previous South standstill on 1 September 2017 at 02:03 in ♑ Capricorn, when Moon has reached southern declination of ∠-19.393°. Next 10 days the lunar orbit moves northward to face North declination of ∠19.438° in the next northern standstill on 14 September 2017 at 13:00 in ♋ Cancer.

Syzygy in 1 day

After 1 day on 6 September 2017 at 07:03 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
