First Quarter on . The illuminated surface of the moon is 56% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 10 December 2040 at 23:30 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 leaving the last ∠3° of ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.
Next Full Moon is the Cold Moon of December 2040 after 7 days on 18 December 2040 at 12:16.
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 0.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1940" and ∠1949".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 506 of Meeus index or 1459 from Brown series.
The length of this lunation is 29 days, 11 hours and 35 minutes and it is 1 hour 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 1 hour and 9 minutes shorter than the mean synodic month length. It is 5 hours 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 ∠323.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠342.7°.
4 days since point of perigee on 6 December 2040 at 13:20 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 22 December 2040 at 13:29 in ♌ Leo.
The Moon is 369 467 km (229 576 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 405 778 km (252 139 mi).
8 days after descending node on 3 December 2040 at 01:02 in ♏ Scorpio 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 15 December 2040 at 21:13 in ♉ Taurus.
5 days since the last southern standstill on 6 December 2040 at 01:37 in ♑ Capricorn when the Moon has reached South declination of ∠-26.791° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠26.761° at the point of next northern standstill on 19 December 2040 at 10:11 in ♋ Cancer.
22 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 7 days on 18 December 2040 at 12:16 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.
