Synodic month length 29.82 days

The length of the lunation is 29 days, 19 hours and 47 minutes. This is the year's longest synodic month of 2018. It is 59 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 longer than mean

The length of the current synodic month is 7 hours and 3 minutes longer than the mean synodic month length and it is the longest synodic month length of 21st century.

True anomaly ∠173.3°

At the beginning of the lunation cycle the true anomaly is ∠173.3°. At the beginning of next synodic month the true anomaly is going to be ∠198.1°.

Moon after perigee

6 days after point of perigee on 1 January 2018 at 21:54 in ♋ Cancer. 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 15 January 2018 at 02:10 in ♑ Capricorn.

Moon after northern standstill

6 days since the previous standstill on 2 January 2018 at 00:01 in ♋ Cancer when the Moon has reached North declination of ∠20.055°, the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-20.048° at the point of next southern standstill on 15 January 2018 at 16:28 in ♑ Capricorn.

Syzygy in 8 days

In 8 days on 17 January 2018 at 02:17 in ♑ Capricorn 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.
