Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♋ Cancer

Moon is passing about ∠8° of ♋ Cancer tropical zodiac sector.

Upcoming main Moon phases

Hunter Moon after 21 days

Next Full Moon is the Hunter Moon of October after 21 days on 18 October 2013 at 23:38.

Apparent angular diameter ∠1768"

Lunar disc appears visually 7.98% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1915".

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.

Lunation 169 / 1122

Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 169 of Meeus index or 1122 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.54 days

Length of current 169 lunation is 29 days, 12 hours and 58 minutes. 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 lunation true anomaly is ∠249.2°. At the 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 in apogee

Moon reaches point of apogee at 23:06 on this date, 11 days after perigee on 27 September 2013 at 18:17. Lunar orbit starts getting closer, while the Moon moves inward the Earth 13 days ahead until next perigee on 10 October 2013 at 23:06.

Distance to Moon 404 309 km

This apogee Moon is 404 309 km (251 226 mi) away from Earth. It is 1 099 km farther than mean apogee distance, but it is still 2 400 km closer than the farthest for 21st century.

Moon after descending node

4 days after its descending node on 22 September 2013 at 13:48, the Moon follows the southern part of its orbit for the next 9 days untill it crosses the ecliptic from South to North in ascending node on 6 October 2013 at 22:08.

Draconic month

17 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 after northern standstill

1 day 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 12 days to face South declination of ∠-19.537° in the next southern standstill on 9 October 2013 at 23:52.

Syzygy in 7 days

After 7 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 5 October 2013 at 00:35.
