Synodic month length 29.39 days

The length of the lunation is 29 days, 9 hours and 19 minutes. It is 1 hour and 51 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 3 hours and 25 minutes shorter than the mean synodic month length. It is 2 hours and 44 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠321.4°

At the beginning of the lunation cycle the true anomaly is ∠321.4°. At the beginning of next synodic month the true anomaly is going to be ∠340.4°.

Moon after perigee

4 days after point of perigee on 30 March 2017 at 12:39 in ♉ Taurus. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next apogee on 15 April 2017 at 10:05 in ♐ Sagittarius.

Distance to Moon 369 698 km

The Moon is 369 698 km (229 720 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 478 km (251 952 mi).

Moon before ascending node

9 days after descending node on 25 March 2017 at 15:41 in ♒ Aquarius. The Moon is located south of the ecliptic over the following 2 days, until the lunar orbit crosses from South to North in ascending node on 7 April 2017 at 09:14 in ♍ Virgo.

Moon after northern standstill

1 day since the previous standstill on 3 April 2017 at 06:12 in ♋ Cancer when the Moon has reached North declination of ∠18.984°, the lunar orbit is extending southward over the next 13 days to face maximum declination of ∠-19.095° at the point of next southern standstill on 17 April 2017 at 13:12 in ♑ Capricorn.

Syzygy in 6 days

In 6 days on 11 April 2017 at 06:08 in ♎ Libra the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
