Moon is passing about ∠5° of ♎ Libra tropical zodiac sector.

Upcoming main Moon phases

Hunter Moon after 14 days

Next Full Moon is the Hunter Moon of October after 14 days on 18 October 2013 at 23:38.

Apparent angular diameter

Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1856" and ∠1919".

Spring tide

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 169 / 1122

At 11:36 on this date the Moon completes the old and enters a new synodic month with lunation 169 of Meeus index or 1122 from Brown series.

Previous | Next

Synodic month length 29.54 days

29 days, 12 hours and 58 minutes is the length of new lunation 169. It is 43 minutes longer than next lunation 170.

Lunation length longer than mean

Length of current synodic month is 14 minutes longer than the mean length of synodic month, but it is still 6 hours and 49 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠249.2°

This New Moon true anomaly is ∠249.2°. At beginning of next synodic month true anomaly is ∠285.3°. The length of upcoming synodic months decreases since the true anomaly gets closer to the value of New Moon at point of perigee (∠0°or∠360°).

Moon before perigee

6 days after point of apogee on 27 September 2013 at 18:17, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 6 days until it gets to the point of perigee on 10 October 2013 at 23:06.

Distance to Moon 386 160 km

Moon is 386 160 km (239 949 mi) away from Earth on this date. At previous apogee point before 6 days, distance is 404 309 km (251 226 mi). Moon moves closer next 6 days until perigee, when Earth-Moon distance reaches 369 813 km (229 791 mi).

Moon before ascending node

11 days after its descending node on 22 September 2013 at 13:48, the Moon follows the southern part of its orbit for the next 2 days untill it crosses the ecliptic from South to North in ascending node on 6 October 2013 at 22:08.

Draconic month

24 days after its beginning, the Moon is moving from the second to the final part of current draconic month.

Previous | Current draconic month | Next

Moon before southern standstill

8 days after previous North standstill on 26 September 2013 at 01:03, when Moon reaches northern declination of ∠19.599°, lunar orbit moves southward for the next 5 days to face South declination of ∠-19.537° in the next southern standstill on 9 October 2013 at 23:52.

Sun-Moon-Earth syzygy

The Moon is in New Moon conjunction with the Sun on this date and this alignment forms Sun-Moon-Earth syzygy.
