Full Moon on . The illuminated surface of the moon is 100%. The lunar cycle is 14 days old.
* The exact date and time of this Full Moon phase is on 20 September 2021 at 23:55 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 ∠22° of ♓ Pisces tropical zodiac sector.
The Full Moon these days is the Harvest of September 2021.
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 3.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1843" and ∠1911".
The Moon is 14 days old and navigating through the middle part of the current synodic month. This is lunation 268 of Meeus index or 1221 from Brown series.
The length of this lunation is 29 days, 10 hours and 14 minutes and it is 5 minutes longer than the upcoming lunation's length. 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 2 hours and 30 minutes shorter than the mean synodic month length. It is 3 hours and 39 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 ∠297.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠323.3°.
9 days since point of perigee on 11 September 2021 at 10:05 in ♏ Scorpio the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next apogee on 26 September 2021 at 21:44 in ♊ Gemini.
The Moon is 388 845 km (241 617 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 404 641 km (251 432 mi).
7 days after descending node on 12 September 2021 at 16:35 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 26 September 2021 at 07:33 in ♊ Gemini.
5 days since the last southern standstill on 15 September 2021 at 03:48 in ♑ Capricorn when the Moon has reached South declination of ∠-25.980° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠26.109° at the point of next northern standstill on 29 September 2021 at 08:26 in ♋ Cancer.
21 days since the beginning of this draconic month in ♊ Gemini 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.
