Synodic month length 29.49 days

The length of the lunation is 29 days, 11 hours and 41 minutes. It is 1 hour and 3 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 shorter than mean

The length of the current synodic month is 1 hour and 3 minutes shorter than the mean synodic month length. It is 5 hours and 6 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠59.2°

At the beginning of the lunation cycle the true anomaly is ∠59.2°. At the beginning of next synodic month the true anomaly is going to be ∠92.6°.

Moon after perigee

1 day after point of perigee on 11 May 2023 at 04:57 in ♒ Aquarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 13 days, until the Moon reaches the point of next apogee on 26 May 2023 at 01:39 in ♌ Leo.

Distance to Moon 363 395 km

The Moon is 363 395 km (225 803 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 404 510 km (251 351 mi).

Moon before ascending node

7 days after descending node on 4 May 2023 at 21:57 in ♎ Libra. The Moon is located south of the ecliptic over the following 5 days, until the lunar orbit crosses from South to North in ascending node on 17 May 2023 at 19:36 in ♈ Aries.

Moon after southern standstill

3 days since the previous standstill on 9 May 2023 at 09:01 in ♑ Capricorn when the Moon has reached South declination of ∠-27.937°, the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠27.903° at the point of next northern standstill on 22 May 2023 at 14:08 in ♊ Gemini.

Syzygy in 7 days

In 7 days on 19 May 2023 at 15:53 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.
