Synodic month length 29.65 days

The length of the lunation is 29 days, 15 hours and 32 minutes. It is 1 hour and 27 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 hours and 48 minutes longer than the mean synodic month length. It is 4 hours and 15 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠232.5°

At the beginning of the lunation cycle the true anomaly is ∠232.5°. At the beginning of next synodic month the true anomaly is going to be ∠269.5°.

Moon before apogee

12 days after point of apogee on 10 October 2023 at 03:41 in ♌ Leo. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 3 days, until the Moon reaches the point of next perigee on 26 October 2023 at 02:53 in ♓ Pisces.

Distance to Moon 365 513 km

The Moon is 365 513 km (227 119 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 364 873 km (226 722 mi).

Moon before ascending node

7 days after descending node on 15 October 2023 at 01:11 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 28 October 2023 at 03:14 in ♈ Aries.

Moon after southern standstill

2 days since the previous standstill on 20 October 2023 at 09:19 in ♑ Capricorn when the Moon has reached South declination of ∠-28.305°, the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠28.288° at the point of next northern standstill on 2 November 2023 at 05:12 in ♋ Cancer.

Syzygy in 6 days

In 6 days on 28 October 2023 at 20:24 in ♈ Aries 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.
