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 25 May 2013 at 04:25 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 ∠9° of ♐ Sagittarius tropical zodiac sector.
The Full Moon these days is the Flower of May 2013.
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 3.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1967" and ∠1894".
The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 165 of Meeus index or 1118 from Brown series.
The length of this lunation is 29 days, 15 hours and 28 minutes and it is 10 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2013. 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 2 hours and 44 minutes longer than the mean synodic month length. It is 4 hours and 19 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠143.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠168.8°.
11 days since point of apogee on 13 May 2013 at 13:31 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 26 May 2013 at 01:45 in ♐ Sagittarius.
The Moon is 364 403 km (226 430 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 358 375 km (222 684 mi).
1 day after ascending node on 24 May 2013 at 00:40 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 6 June 2013 at 00:59 in ♉ Taurus.
12 days since the last northern standstill on 12 May 2013 at 12:30 in ♊ Gemini when the Moon has reached North declination of ∠20.170° the lunar orbit is extending southward over the next day to face maximum declination of ∠-20.182° at the point of next southern standstill on 26 May 2013 at 04:47 in ♐ Sagittarius.
1 day since the beginning of this draconic month in ♏ Scorpio 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.
