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 20 September 2051 at 10:11 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 ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.
The Full Moon these days is the Harvest of September 2051.
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 2.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1960" and ∠1911".
The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 639 of Meeus index or 1592 from Brown series.
The length of this lunation is 29 days, 16 hours and 14 minutes and it is 1 hour and 58 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 3 hours and 29 minutes longer than the mean synodic month length. It is 3 hours and 33 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 ∠137° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠163.9°.
11 days since point of apogee on 9 September 2051 at 04:18 in ♏ Scorpio 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 21 September 2051 at 12:20 in ♈ Aries.
The Moon is 365 661 km (227 211 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 358 920 km (223 023 mi).
11 days after ascending node on 8 September 2051 at 15:18 in ♎ Libra the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 22 September 2051 at 03:59 in ♈ Aries.
6 days since the last southern standstill on 13 September 2051 at 15:30 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.758° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠18.704° at the point of next northern standstill on 26 September 2051 at 07:36 in ♊ Gemini.
11 days since the beginning of this draconic month in ♎ Libra 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.
