New lunation 388 / 1341

At 07:17 on this date the Moon completes the old and enters a new synodic month with lunation 388 of Meeus index or 1341 from Brown series.


Synodic month length 29.63 days

29 days, 15 hours and 7 minutes is the length of new lunation 388. It is 9 minutes shorter than next lunation 389 length.

Lunation length longer than mean

Length of current synodic month is 2 hours and 23 minutes longer than the mean length of synodic month, but it is still 4 hours and 40 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠139.8°

This New Moon true anomaly is ∠139.8°. At beginning of next synodic month true anomaly will be ∠165.9°. 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 apogee

12 days after point of perigee on 9 May 2031 at 07:28 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 25 May 2031 at 02:08 in ♋ Cancer.

Previous perigeeNext apogee

Distance to Moon 400 573 km

Moon is 400 573 km (248 905 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 405 723 km (252 105 mi).

Moon in descending node

Moon is in descending node in ♉ Taurus at 03:26 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 13 days to meet ascending node on 4 June 2031 at 09:20 in ♏ Scorpio.

Moon before northern standstill

12 days after previous South standstill on 9 May 2031 at 07:56 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.092°. Next day the lunar orbit moves northward to face North declination of ∠21.091° in the next northern standstill on 22 May 2031 at 19:41 in ♊ Gemini.
