Length of current synodic month is 2 hours and 30 minutes shorter than the mean length of synodic month, but it is still 3 hours and 39 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠297.8°

This lunation true anomaly is ∠297.8°. At the beginning of next synodic month true anomaly will be ∠323.3°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon before perigee

11 days after point of apogee on 30 August 2021 at 02:22 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 11 September 2021 at 10:05 in ♏ Scorpio.
