Lunar orbit position on

True anomaly ∠147°

This New Moon true anomaly is ∠147°. At beginning of next synodic month true anomaly will be ∠173.3°. 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

12 days after point of perigee on 4 December 2017 at 08:42 in ♊ Gemini. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 2 days, until it get to the point of next apogee on 19 December 2017 at 01:27 in ♑ Capricorn.
