Synodic month length 29.69 days

The length of the lunation is 29 days, 16 hours and 29 minutes. This is the year's longest synodic month of 2021. It is 36 minutes longer 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 3 hours and 45 minutes longer than the mean synodic month length. It is 3 hours and 18 minutes shorter compared to 21st century's longest synodic month length.

True anomaly ∠154.8°

At the beginning of the lunation cycle the true anomaly is ∠154.8°. At the beginning of next synodic month the true anomaly is going to be ∠178.9°.

Moon after perigee

6 days after point of perigee on 27 April 2021 at 15:24 in ♏ Scorpio. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 7 days, until the Moon reaches the point of next apogee on 11 May 2021 at 21:54 in ♉ Taurus.

Moon after southern standstill

3 days since the previous standstill on 1 May 2021 at 09:37 in ♑ Capricorn when the Moon has reached South declination of ∠-25.591°, the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠25.640° at the point of next northern standstill on 15 May 2021 at 22:25 in ♋ Cancer.

Syzygy in 7 days

In 7 days on 11 May 2021 at 19:00 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.
