Full Moon on . The illuminated surface of the moon is 100%. The lunar cycle is 15 days old.
* The exact date and time of this Full Moon phase is on 12 September 2011 at 09:27 UTC.
The moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.

Main moon phases of the following lunar cycle.
Moon is passing about ∠21° of ♓ Pisces tropical zodiac sector.
The Full Moon these days is the Harvest of September 2011.
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1780" and ∠1907".
The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 144 of Meeus index or 1097 from Brown series.
The length of this lunation is 29 days, 8 hours and 5 minutes and it is 42 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2011. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 4 hours and 39 minutes shorter than the mean synodic month length. It is 1 hour and 30 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠333.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠350.1°.
12 days since point of perigee on 30 August 2011 at 17:35 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 15 September 2011 at 06:23 in ♈ Aries.
The Moon is 402 728 km (250 244 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 406 068 km (252 319 mi).
7 days after ascending node on 5 September 2011 at 07:36 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 19 September 2011 at 19:38 in ♊ Gemini.
7 days since the last southern standstill on 5 September 2011 at 05:01 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.047° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠22.890° at the point of next northern standstill on 19 September 2011 at 20:05 in ♊ Gemini.
7 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the beginning to the first part of the lunar cycle.
The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
