Synodic month length 29.55 days

The length of the lunation is 29 days, 13 hours and 8 minutes. It is 1 hour and 12 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 24 minutes longer than the mean synodic month length. It is 6 hours and 39 minutes shorter compared to 21st century's longest synodic month length.

True anomaly ∠70.3°

At the beginning of the lunation cycle the true anomaly is ∠70.3°. At the beginning of next synodic month the true anomaly is going to be ∠106.4°.

Moon before perigee

8 days after point of perigee on 11 April 2031 at 19:13 in ♐ Sagittarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next apogee on 27 April 2031 at 10:30 in ♋ Cancer.

Moon before descending node

9 days after ascending node on 10 April 2031 at 14:56 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 3 days, until the lunar orbit crosses from North to South in descending node on 23 April 2031 at 20:23 in ♉ Taurus.

Moon before northern standstill

8 days since the previous standstill on 12 April 2031 at 00:31 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.160°, the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠21.107° at the point of next northern standstill on 25 April 2031 at 12:37 in ♊ Gemini.

Syzygy in 1 day

In 1 day on 21 April 2031 at 16:57 in ♈ Aries the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
