Lunar orbit position on

True anomaly ∠267.3°

This lunation true anomaly is ∠267.3°. At the beginning of next synodic month true anomaly will be ∠299.7°. 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

14 days after point of apogee on 17 April 2001 at 06:06 in ♒ Aquarius. 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 2 May 2001 at 03:37 in ♍ Virgo.

Moon after northern standstill

2 days after previous North standstill on 28 April 2001 at 16:18 in ♋ Cancer, when Moon has reached northern declination of ∠23.248°. Next 10 days the lunar orbit moves southward to face South declination of ∠-23.329° in the next southern standstill on 11 May 2001 at 20:26 in ♑ Capricorn.
