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°).

Moon before northern standstill

8 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 5 days to face maximum declination of ∠27.903° at the point of next northern standstill on 22 May 2023 at 14:08 in ♊ Gemini.

Previous standstillNext standstill

Syzygy in 2 days

In 2 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.
