Lunar orbit position on

True anomaly ∠135.6°

This New Moon true anomaly is ∠135.6°. At beginning of next synodic month true anomaly will be ∠164.3°. 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 apogee

8 days after point of perigee on 1 January 2010 at 20:36 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 6 days, until it get to the point of next apogee on 17 January 2010 at 01:40 in ♒ Aquarius.

Moon before ascending node

8 days after its descending node on 1 January 2010 at 12:30 in ♋ Cancer, the Moon is following the southern part of its orbit for the next 4 days, until it will cross the ecliptic from South to North in ascending node on 14 January 2010 at 23:18 in ♑ Capricorn.

Moon before southern standstill

11 days after previous North standstill on 30 December 2009 at 10:09 in ♊ Gemini, when Moon has reached northern declination of ∠25.787°. Next day the lunar orbit moves southward to face South declination of ∠-25.796° in the next southern standstill on 12 January 2010 at 08:33 in ♐ Sagittarius.

Syzygy in 4 days

After 4 days on 15 January 2010 at 07:11 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
