The length of the lunation is 29 days, 13 hours and 42 minutes. It is 2 hours and 48 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 after northern standstill

3 days since the previous standstill on 11 October 2017 at 18:21 in ♋ Cancer when the Moon has reached North declination of ∠19.616°, the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-19.741° at the point of next southern standstill on 25 October 2017 at 18:13 in ♑ Capricorn.
