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 22 August 2021 at 12:02 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 first ∠0° of ♒ Aquarius tropical zodiac sector.
The Full Moon these days is the Sturgeon of August 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 1.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1877" and ∠1897".
The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 267 of Meeus index or 1220 from Brown series.
The length of this lunation is 29 days, 11 hours and 2 minutes and it is 48 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 1 hour and 42 minutes shorter than the mean synodic month length. It is 4 hours and 27 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 ∠264.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠297.8°.
5 days since point of perigee on 17 August 2021 at 09:23 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 30 August 2021 at 02:22 in ♊ Gemini.
The Moon is 381 777 km (237 225 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 404 100 km (251 096 mi).
5 days after descending node on 16 August 2021 at 16:04 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 30 August 2021 at 05:13 in ♊ Gemini.
3 days since the last southern standstill on 18 August 2021 at 22:24 in ♑ Capricorn when the Moon has reached South declination of ∠-25.761° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠25.868° at the point of next northern standstill on 2 September 2021 at 00:23 in ♋ Cancer.
19 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.
