Lunation length shorter than mean

Length of current synodic month is 5 hours and 34 minutes shorter than the mean length of synodic month, but it is still 35 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠356°

This New Moon true anomaly is ∠356°. At beginning of next synodic month true anomaly will be ∠11.2°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon before southern standstill

7 days after previous North standstill on 12 July 2018 at 12:01 in ♋ Cancer, when Moon has reached northern declination of ∠20.761°. Next 5 days the lunar orbit moves southward to face South declination of ∠-20.755° in the next southern standstill on 25 July 2018 at 20:55 in ♑ Capricorn.

Syzygy in 7 days

After 7 days on 27 July 2018 at 20:20 in ♑ Capricorn, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
