Full Moon on . The illuminated surface of the moon is 99%. The lunar cycle is 15 days old.
* The exact date and time of this Full Moon phase is on 10 December 2011 at 14:36 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 leaving the last ∠1° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.
The Full Moon these days is the Cold of December 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 ∠1818" and ∠1949".
The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 147 of Meeus index or 1100 from Brown series.
The length of this lunation is 29 days, 11 hours and 57 minutes and it is 1 hour and 36 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 47 minutes shorter than the mean synodic month length. It is 5 hours and 22 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 ∠21.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠42.1°.
5 days since point of apogee on 6 December 2011 at 01:13 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 22 December 2011 at 02:56 in ♏ Scorpio.
The Moon is 394 164 km (244 922 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 364 801 km (226 677 mi).
1 day after descending node on 10 December 2011 at 07:04 in ♊ Gemini the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 23 December 2011 at 11:36 in ♐ Sagittarius.
1 day since the last northern standstill on 10 December 2011 at 13:37 in ♊ Gemini when the Moon has reached North declination of ∠22.554° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-22.554° at the point of next southern standstill on 23 December 2011 at 17:25 in ♐ Sagittarius.
15 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final 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.
