Synodic month length 29.53 days

The length of the lunation is 29 days, 12 hours and 46 minutes. It is 2 hours and 55 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 2 minutes longer than the mean synodic month length. It is 7 hours and 1 minute shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠262.6°

At the beginning of the lunation cycle the true anomaly is ∠262.6°. At the beginning of next synodic month the true anomaly is going to be ∠296.5°.

Moon before apogee

14 days after point of apogee on 11 March 2018 at 09:13 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next day, until the Moon reaches the point of next perigee on 26 March 2018 at 17:17 in ♋ Cancer.

Distance to Moon 363 299 km

The Moon is 363 299 km (225 744 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 369 104 km (229 351 mi).

Moon before ascending node

11 days after descending node on 14 March 2018 at 03:48 in ♒ Aquarius. The Moon is located south of the ecliptic over the following day, until the lunar orbit crosses from South to North in ascending node on 27 March 2018 at 10:56 in ♌ Leo.

Draconic month

25 days since the beginning of current draconic month in ♌ Leo, the Moon is navigating from the second to the final part of the cycle.

Moon at northern standstill

At 02:04 the Moon is meeting its standstill point to reach North declination of ∠20.210°. Over the next 13 days the lunar orbit is going to extend southward to face maximum declination of ∠-20.320° at the point of next standstill in ♑ Capricorn on 7 April 2018 at 14:37.

Syzygy in 6 days

In 6 days on 31 March 2018 at 12:37 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.
