First Quarter on . The illuminated surface of the moon is 63% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 12 December 2078 at 07:52 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 ∠7° of ♈ Aries tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2078 after 5 days on 18 December 2078 at 23:34.
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 0.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1939" and ∠1949".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 976 of Meeus index or 1929 from Brown series.
The length of this lunation is 29 days, 18 hours and 42 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 5 hours and 58 minutes longer than the mean synodic month length. It is 1 hour and 5 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 ∠196.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠225.6°.
10 days since point of apogee on 2 December 2078 at 15:34 in ♏ Scorpio the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next perigee on 17 December 2078 at 21:10 in ♊ Gemini.
The Moon is 369 755 km (229 755 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 358 828 km (222 965 mi).
11 days after descending node on 1 December 2078 at 18:16 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 December 2078 at 19:09 in ♉ Taurus.
6 days since the last southern standstill on 6 December 2078 at 12:06 in ♑ Capricorn when the Moon has reached South declination of ∠-27.555° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠27.536° at the point of next northern standstill on 19 December 2078 at 14:06 in ♊ Gemini.
25 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.
In 5 days on 18 December 2078 at 23:34 in ♊ Gemini 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.
