First Quarter on . The illuminated surface of the moon is 61% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 22 December 2039 at 10:01 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 ∠14° of ♈ Aries tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2039 after 7 days on 30 December 2039 at 12:37.
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 5.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1845" and ∠1951".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 494 of Meeus index or 1447 from Brown series.
The length of this lunation is 29 days, 10 hours and 53 minutes and it is 6 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 51 minutes shorter than the mean synodic month length. It is 4 hours and 18 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 ∠356.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠12.4°.
7 days since point of perigee on 15 December 2039 at 20:51 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 6 days until the Moon reaches the point of next apogee on 29 December 2039 at 16:34 in ♊ Gemini.
The Moon is 388 588 km (241 457 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 355 km (252 497 mi).
8 days after descending node on 14 December 2039 at 23:54 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 28 December 2039 at 08:24 in ♊ Gemini.
6 days since the last southern standstill on 16 December 2039 at 19:27 in ♑ Capricorn when the Moon has reached South declination of ∠-25.464° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠25.448° at the point of next northern standstill on 30 December 2039 at 16:29 in ♋ Cancer.
22 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 7 days on 30 December 2039 at 12:37 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.
