Moon phase and lunation details

1 day after Last Quarter

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Next Full Moon is the Harvest Moon of September 2013 after 20 days on 19 September 2013 at 11:13.

Upcoming main Moon phases

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 168 / 1121

The Moon is 23 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 168 of Meeus index or 1121 from Brown series.

Synodic month length 29.57 days

Length of current 168 lunation is 29 days, 13 hours and 45 minutes. It is 47 minutes longer than next lunation 169 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 1 minute longer than the mean length of synodic month, but it is still 6 hours and 2 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠216.9°

This lunation true anomaly is ∠216.9°. At the beginning of next synodic month true anomaly will be ∠249.2°. 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 19 August 2013 at 01:26 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 30 August 2013 at 23:46 in ♋ Cancer.

Distance to Moon 404 078 km

Moon is 404 078 km (251 082 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 404 883 km (251 583 mi).

Moon after descending node

3 days after its descending node on 26 August 2013 at 08:19 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 11 days, until it will cross the ecliptic from South to North in ascending node on 9 September 2013 at 17:29 in ♏ Scorpio.

Moon in northern standstill

At 17:03 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠19.801°. Next 14 days the lunar orbit will move in opposite southward direction to face South declination of ∠-19.685° in its southern standstill point on 12 September 2013 at 18:30 in ♐ Sagittarius.

Syzygy in 6 days

After 6 days on 5 September 2013 at 11:36 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
