Next Full Moon is the Beaver Moon of November 2011 after 21 days on 10 November 2011 at 20:16.

Upcoming main Moon phases

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 145 of Meeus index or 1098 from Brown series.

Synodic month length 29.37 days

Length of current 145 lunation is 29 days, 8 hours and 47 minutes. It is 1 hour and 27 minutes shorter than next lunation 146 length.

Lunation length shorter than mean

Length of current synodic month is 3 hours and 57 minutes shorter than the mean length of synodic month, but it is still 2 hours and 12 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠350.1°

This New Moon true anomaly is ∠350.1°. At beginning of next synodic month true anomaly will be ∠5.3°. 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 perigee

8 days after point of apogee on 12 October 2011 at 11:43 in ♈ Aries. 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 26 October 2011 at 12:26 in ♎ Libra.

Distance to Moon 380 243 km

Moon is 380 243 km (236 272 mi) away from Earth on this date. Moon moves closer next 6 days until perigee, when Earth-Moon distance will reach 357 051 km (221 861 mi).

Moon after descending node

3 days after its descending node on 16 October 2011 at 21:01 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 9 days, until it will cross the ecliptic from South to North in ascending node on 29 October 2011 at 14:59 in ♐ Sagittarius.

Moon after northern standstill

3 days after previous North standstill on 17 October 2011 at 02:06 in ♊ Gemini, when Moon has reached northern declination of ∠22.665°. Next 9 days the lunar orbit moves southward to face South declination of ∠-22.609° in the next southern standstill on 29 October 2011 at 20:17 in ♐ Sagittarius.
