New lunation 387 / 1340

At 16:57 on this date the Moon completes the old and enters a new synodic month with lunation 387 of Meeus index or 1340 from Brown series.


Synodic month length 29.6 days

29 days, 14 hours and 20 minutes is the length of new lunation 387. It is 47 minutes shorter than next lunation 388 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 36 minutes longer than the mean length of synodic month, but it is still 5 hours and 27 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠106.4°

This New Moon true anomaly is ∠106.4°. At beginning of next synodic month true anomaly will be ∠139.8°. 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

9 days after point of perigee on 11 April 2031 at 19:13 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 5 days, until it get to the point of next apogee on 27 April 2031 at 10:30 in ♋ Cancer.

Distance to Moon 391 098 km

Moon is 391 098 km (243 017 mi) away from Earth on this date. Moon moves farther next 5 days until apogee, when Earth-Moon distance will reach 404 758 km (251 505 mi).

Moon before descending node

10 days after its ascending node on 10 April 2031 at 14:56 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 2 days, until it will cross the ecliptic from North to South in descending node on 23 April 2031 at 20:23 in ♉ Taurus.

Moon before northern standstill

9 days after previous South standstill on 12 April 2031 at 00:31 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.160°. Next 4 days the lunar orbit moves northward to face North declination of ∠21.107° in the next northern standstill on 25 April 2031 at 12:37 in ♊ Gemini.
