This New Moon true anomaly is ∠53.8°. At beginning of next synodic month true anomaly will be ∠87°. 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°).
1 day after point of perigee on 3 February 2021 at 19:33 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 13 days, until it get to the point of next apogee on 18 February 2021 at 10:22 in ♉ Taurus.
