Synodic month length 29.66 days

Length of current 193 lunation is 29 days, 15 hours and 48 minutes. It is 1 hour and 36 minutes shorter than next lunation 194 length.

Lunation length longer than mean

Length of current synodic month is 3 hours and 4 minutes longer than the mean length of synodic month, but it is still 3 hours and 59 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠144.1°

This New Moon true anomaly is ∠144.1°. At beginning of next synodic month true anomaly will be ∠169.3°. 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 perigee

1 day after point of perigee on 30 August 2015 at 15:24 in ♓ Pisces. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 12 days, until it get to the point of next apogee on 14 September 2015 at 11:28 in ♎ Libra.

Distance to Moon 364 027 km

Moon is 364 027 km (226 196 mi) away from Earth on this date. Moon moves farther next 12 days until apogee, when Earth-Moon distance will reach 406 466 km (252 566 mi).

Moon after descending node

1 day after its descending node on 31 August 2015 at 10:16 in ♈ Aries, the Moon is following the southern part of its orbit for the next 12 days, until it will cross the ecliptic from South to North in ascending node on 14 September 2015 at 04:38 in ♎ Libra.

Moon before northern standstill

7 days after previous South standstill on 25 August 2015 at 03:44 in ♐ Sagittarius, when Moon has reached southern declination of ∠-18.206°. Next 5 days the lunar orbit moves northward to face North declination of ∠18.163° in the next northern standstill on 6 September 2015 at 17:06 in ♊ Gemini.

Syzygy in 11 days

After 11 days on 13 September 2015 at 06:41 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
