Lunar orbit position on

True anomaly ∠11°

This New Moon true anomaly is ∠11°. At beginning of next synodic month true anomaly will be ∠27.9°. 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 perigee

9 days after point of apogee on 6 July 2017 at 04:27 in ♐ Sagittarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 6 days, until it get to the point of next perigee on 21 July 2017 at 17:09 in ♊ Gemini.

Moon before northern standstill

7 days after previous South standstill on 8 July 2017 at 10:49 in ♑ Capricorn, when Moon has reached southern declination of ∠-19.440°. Next 6 days the lunar orbit moves northward to face North declination of ∠19.413° in the next northern standstill on 21 July 2017 at 22:11 in ♋ Cancer.
