First Quarter on . The illuminated surface of the moon is 45% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 21 December 2020 at 23:41 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 about ∠25° of ♓ Pisces tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2020 after 8 days on 30 December 2020 at 03:28.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunar disc appears visually 8.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1794" and ∠1951".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 259 of Meeus index or 1212 from Brown series.
The length of this lunation is 29 days, 12 hours and 44 minutes and it is 1 hour and 21 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 equal to the mean synodic month length. It is %hours_to_shortest% and %minutes_to_shortest% longer than the 21st century's shortest and %hours_to_longest% and %minutes_to_longest% shorter than the 21st century's longest synodic months.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠30.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠53.8°.
8 days since point of perigee on 12 December 2020 at 20:42 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 3 days until the Moon reaches the point of next apogee on 24 December 2020 at 16:32 in ♈ Aries.
The Moon is 399 554 km (248 271 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 405 010 km (251 662 mi).
7 days after descending node on 14 December 2020 at 11:03 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 28 December 2020 at 15:03 in ♊ Gemini.
5 days since the last southern standstill on 15 December 2020 at 22:23 in ♑ Capricorn when the Moon has reached South declination of ∠-24.879° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠24.868° at the point of next northern standstill on 30 December 2020 at 07:53 in ♋ Cancer.
20 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.
In 8 days on 30 December 2020 at 03:28 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.
