Lunar orbit position on

True anomaly ∠296.5°

This lunation true anomaly is ∠296.5°. At the beginning of next synodic month true anomaly will be ∠321.7°. 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

6 days after point of apogee on 6 May 2018 at 00:35 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 17 May 2018 at 21:06 in ♊ Gemini.

Moon before northern standstill

7 days after previous South standstill on 4 May 2018 at 23:00 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.562°. Next 6 days the lunar orbit moves northward to face North declination of ∠20.652° in the next northern standstill on 18 May 2018 at 15:02 in ♋ Cancer.

Syzygy in 2 days

After 2 days on 15 May 2018 at 11:48 in ♉ Taurus, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
