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 19 December 2021 at 04:36 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 passing first ∠1° of ♋ Cancer tropical zodiac sector.
The Full Moon these days is the Cold of December 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 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1950".
The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 271 of Meeus index or 1224 from Brown series.
The length of this lunation is 29 days, 10 hours and 50 minutes and it is 23 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 1 hour and 54 minutes shorter than the mean synodic month length. It is 4 hours and 15 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 ∠358.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠13.9°.
1 day since point of apogee on 18 December 2021 at 02:16 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next perigee on 1 January 2022 at 23:00 in ♐ Sagittarius.
The Moon is 404 809 km (251 537 mi) away from Earth and getting closer over the next 13 days until the point perigee when Earth-Moon distance is going to be 358 037 km (222 474 mi).
2 days after ascending node on 17 December 2021 at 00:12 in ♊ Gemini 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 31 December 2021 at 01:07 in ♐ Sagittarius.
13 days since the last southern standstill on 6 December 2021 at 02:25 in ♑ Capricorn when the Moon has reached South declination of ∠-26.331° the lunar orbit is extending northward over the next day to face maximum declination of ∠26.306° at the point of next northern standstill on 20 December 2021 at 04:32 in ♋ Cancer.
2 days since the beginning of this draconic month in ♊ Gemini 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.
