First Quarter on . The illuminated surface of the moon is 54% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 21 December 2050 at 04:15 UTC.
The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Main moon phases of the following lunar cycle.
Moon is passing first ∠4° of ♈ Aries tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2050 after 6 days on 28 December 2050 at 05:15.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1951".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 630 of Meeus index or 1583 from Brown series.
The length of this lunation is 29 days, 13 hours and 40 minutes and it is 1 hour and 57 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 56 minutes longer than the mean synodic month length. It is 6 hours and 7 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 ∠282.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠313.4°.
1 day since point of perigee on 20 December 2050 at 16:49 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next apogee on 4 January 2051 at 00:04 in ♎ Libra.
The Moon is 363 426 km (225 822 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 404 452 km (251 315 mi).
10 days after ascending node on 11 December 2050 at 00:42 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 24 December 2050 at 02:37 in ♉ Taurus.
7 days since the last southern standstill on 14 December 2050 at 02:00 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.822° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠19.815° at the point of next northern standstill on 27 December 2050 at 00:57 in ♊ Gemini.
10 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first part of the lunar cycle.
In 6 days on 28 December 2050 at 05:15 in ♋ Cancer the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
