Synodic month length 29.58 days

The length of the lunation is 29 days, 13 hours and 55 minutes. It is 1 hour and 11 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 1 hour and 11 minutes longer than the mean synodic month length. It is 5 hours and 52 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠127.4°

At the beginning of the lunation cycle the true anomaly is ∠127.4°. At the beginning of next synodic month the true anomaly is going to be ∠155.7°.

Moon after perigee

5 days after point of perigee on 4 July 2023 at 22:28 in ♑ Capricorn. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next apogee on 20 July 2023 at 06:56 in ♌ Leo.

Distance to Moon 373 847 km

The Moon is 373 847 km (232 298 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 291 km (252 458 mi).

Moon before ascending node

11 days after descending node on 28 June 2023 at 12:22 in ♏ Scorpio. The Moon is located south of the ecliptic over the following day, until the lunar orbit crosses from South to North in ascending node on 11 July 2023 at 01:23 in ♉ Taurus.

Moon before northern standstill

7 days since the previous standstill on 3 July 2023 at 01:23 in ♑ Capricorn when the Moon has reached South declination of ∠-27.840°, the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠27.849° at the point of next northern standstill on 16 July 2023 at 02:40 in ♋ Cancer.

Syzygy in 7 days

In 7 days on 17 July 2023 at 18:32 in ♋ Cancer 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.
