Lunar orbit position on

True anomaly ∠79°

This New Moon true anomaly is ∠79°. At beginning of next synodic month true anomaly will be ∠114.6°. 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 after apogee

1 day after point of apogee on 27 September 2017 at 06:49 in ♐ Sagittarius. 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 9 October 2017 at 05:51 in ♊ Gemini.
