Synodic month length 29.69 days

The length of the lunation is 29 days, 16 hours and 37 minutes. It is 1 hour and 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 3 hours and 53 minutes longer than the mean synodic month length. It is 3 hours and 10 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠176.6°

At the beginning of the lunation cycle the true anomaly is ∠176.6°. At the beginning of next synodic month the true anomaly is going to be ∠200.1°.

Moon before perigee

7 days after point of perigee on 24 April 2100 at 02:13 in ♎ Libra. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next apogee on 7 May 2100 at 05:13 in ♈ Aries.

Distance to Moon 390 023 km

The Moon is 390 023 km (242 349 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 406 376 km (252 510 mi).

Moon before ascending node

10 days after descending node on 21 April 2100 at 05:33 in ♍ Virgo. The Moon is located south of the ecliptic over the following 2 days, until the lunar orbit crosses from South to North in ascending node on 4 May 2100 at 01:19 in ♓ Pisces.

Moon after southern standstill

3 days since the previous standstill on 28 April 2100 at 00:08 in ♑ Capricorn when the Moon has reached South declination of ∠-28.374°, the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠28.277° at the point of next northern standstill on 12 May 2100 at 13:36 in ♊ Gemini.

Syzygy in 7 days

In 7 days on 9 May 2100 at 08:54 in ♉ Taurus 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.
