Synodic month length 29.41 days

The length of the lunation is 29 days, 9 hours and 51 minutes. It is 1 hour and 56 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 2 hours and 53 minutes shorter than the mean synodic month length. It is 3 hours and 16 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠296.5°

At the beginning of the lunation cycle the true anomaly is ∠296.5°. At the beginning of next synodic month the true anomaly is going to be ∠321.7°.

Moon after perigee

2 days after point of perigee on 20 April 2018 at 14:44 in ♊ Gemini. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 12 days, until the Moon reaches the point of next apogee on 6 May 2018 at 00:35 in ♑ Capricorn.

Distance to Moon 364 733 km

The Moon is 364 733 km (226 635 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 404 458 km (251 319 mi).

Moon in ascending node

Moon is in ascending node in ♌ Leo at 12:19 crossing the ecliptic from South to North to meet descending node 13 days later on 7 May 2018 at 10:24 in ♒ Aquarius.

New draconic month

At 12:19 the Moon completes the previous draconic month and enters the new one.

Moon after northern standstill

2 days since the previous standstill on 21 April 2018 at 07:38 in ♋ Cancer when the Moon has reached North declination of ∠20.445°, the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-20.562° at the point of next southern standstill on 4 May 2018 at 23:00 in ♑ Capricorn.

Syzygy in 6 days

In 6 days on 30 April 2018 at 00:58 in ♏ Scorpio 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.
