Upcoming main Moon phases

There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.

New lunation 145 / 1098

At 11:09 on this date the Moon completes the old and enters a new synodic month with lunation 145 of Meeus index or 1098 from Brown series.


Synodic month length 29.37 days

29 days, 8 hours and 47 minutes is the length of new lunation 145. 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

12 days after point of apogee on 15 September 2011 at 06:23 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 28 September 2011 at 01:01 in ♎ Libra.

Distance to Moon 364 034 km

Moon is 364 034 km (226 200 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 357 556 km (222 175 mi).

Moon before ascending node

7 days after its descending node on 19 September 2011 at 19:38 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 4 days, until it will cross the ecliptic from South to North in ascending node on 2 October 2011 at 09:09 in ♐ Sagittarius.

Moon before southern standstill

7 days after previous North standstill on 19 September 2011 at 20:05 in ♊ Gemini, when Moon has reached northern declination of ∠22.890°. Next 4 days the lunar orbit moves southward to face South declination of ∠-22.791° in the next southern standstill on 2 October 2011 at 11:38 in ♐ Sagittarius.
