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 ♊ Gemini

Moon is leaving the last ∠4° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Apparent angular diameter ∠1771"

Lunar disc appears visually 7.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1914".

Next Full Moon is the Hunter Moon of October 2013 after 22 days on 18 October 2013 at 23:38.

Upcoming main Moon phases

The Moon is 21 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.

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 length.

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 will be ∠285.3°. 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 apogee

10 days after point of perigee on 15 September 2013 at 16:34 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 27 September 2013 at 18:17 in ♋ Cancer.

Distance to Moon 404 644 km

Moon is 404 644 km (251 434 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 404 309 km (251 226 mi).

Moon after descending node

3 days after its descending node on 22 September 2013 at 13:48 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 10 days, until it will cross the ecliptic from South to North in ascending node on 6 October 2013 at 22:08 in ♏ Scorpio.

Moon in northern standstill

At 01:03 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠19.599°. Next 13 days the lunar orbit will move in opposite southward direction to face South declination of ∠-19.537° in its southern standstill point on 9 October 2013 at 23:52 in ♐ Sagittarius.

Syzygy in 8 days

After 8 days on 5 October 2013 at 00:35 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
