New lunation 393 / 1346

At 08:21 on this date the Moon completes the old and enters a new synodic month with lunation 393 of Meeus index or 1346 from Brown series.


Synodic month length 29.53 days

29 days, 12 hours and 49 minutes is the length of new lunation 393. It is 53 minutes longer than next lunation 394 length.

Lunation length longer than mean

Length of current synodic month is 5 minutes longer than the mean length of synodic month, but it is still 6 hours and 58 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠281.8°

This lunation true anomaly is ∠281.8°. At the beginning of next synodic month true anomaly will be ∠312.6°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon before perigee

7 days after point of apogee on 9 October 2031 at 06:23 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 6 days, until it get to the point of next perigee on 22 October 2031 at 20:06 in ♑ Capricorn.

Distance to Moon 383 936 km

Moon is 383 936 km (238 567 mi) away from Earth on this date. Moon moves closer next 6 days until perigee, when Earth-Moon distance will reach 370 022 km (229 921 mi).

Moon before ascending node

12 days after its descending node on 3 October 2031 at 22:04 in ♉ Taurus, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 18 October 2031 at 06:54 in ♏ Scorpio.
