Synodic month length 29.46 days

The length of the lunation is 29 days, 11 hours and 1 minute. This is the year's shortest synodic month of 2031. It is 43 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 1 hour and 43 minutes shorter than the mean synodic month length. It is 4 hours and 26 minutes longer compared to 21st century's shortest synodic month length.

True anomaly ∠334.7°

At the beginning of the lunation cycle the true anomaly is ∠334.7°. At the beginning of next synodic month the true anomaly is going to be ∠351.6°.

Moon before perigee

12 days after point of perigee on 15 December 2031 at 21:31 in ♑ Capricorn. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 3 days, until the Moon reaches the point of next apogee on 31 December 2031 at 13:16 in ♌ Leo.

Distance to Moon 402 254 km

The Moon is 402 254 km (249 949 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 406 203 km (252 403 mi).

Moon after descending node

3 days after descending node on 24 December 2031 at 18:44 in ♉ Taurus. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 8 January 2032 at 08:58 in ♏ Scorpio.

Moon after northern standstill

1 day since the previous standstill on 27 December 2031 at 07:41 in ♊ Gemini when the Moon has reached North declination of ∠20.355°, the lunar orbit is extending southward over the next 13 days to face maximum declination of ∠-20.298° at the point of next southern standstill on 10 January 2032 at 16:49 in ♐ Sagittarius.

Sun-Earth-Moon syzygy

The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
