Lunation length shorter than mean

Length of current synodic month is 2 hours and 10 minutes shorter than the mean length of synodic month, but it is still 3 hours and 59 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠338.3°

This lunation true anomaly is ∠338.3°. At the beginning of next synodic month true anomaly will be ∠354.5°. 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 after apogee

2 days after point of apogee on 6 February 2015 at 06:25 in ♍ Virgo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 19 February 2015 at 07:29 in ♓ Pisces.

Moon before southern standstill

8 days after previous North standstill on 31 January 2015 at 00:59 in ♋ Cancer, when Moon has reached northern declination of ∠18.513°. Next 6 days the lunar orbit moves southward to face South declination of ∠-18.402° in the next southern standstill on 14 February 2015 at 17:17 in ♐ Sagittarius.
