The length of the lunation is 29 days, 18 hours and 48 minutes. It is 59 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 6 hours and 4 minutes longer than the mean synodic month length. It is 59 minutes shorter compared to 21st century's longest synodic month length.

Moon before southern standstill

10 days since the previous standstill on 5 December 2017 at 11:43 in ♋ Cancer when the Moon has reached North declination of ∠20.015°, the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-20.062° at the point of next southern standstill on 19 December 2017 at 09:31 in ♑ Capricorn.

Syzygy in 2 days

In 2 days on 18 December 2017 at 06:31 in ♐ Sagittarius 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.
