Synodic month length 29.78 days

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.

Lunar orbit position on

True anomaly ∠147°

At the beginning of the lunation cycle the true anomaly is ∠147°. At the beginning of next synodic month the true anomaly is going to be ∠173.3°.

Moon after perigee

6 days after point of perigee on 4 December 2017 at 08:42 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 8 days, until the Moon reaches the point of next apogee on 19 December 2017 at 01:27 in ♑ Capricorn.

Distance to Moon 378 668 km

The Moon is 378 668 km (235 293 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 406 605 km (252 653 mi).

Moon after ascending node

2 days after ascending node on 8 December 2017 at 00:39 in ♌ Leo. The Moon is located north of the ecliptic over the following 11 days, until the lunar orbit crosses from North to South in descending node on 22 December 2017 at 10:04 in ♒ Aquarius.

Moon after northern standstill

5 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 8 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 7 days

In 7 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.
