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 5 December 2046 at 07:56 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 2046 after 6 days on 13 December 2046 at 09:55.
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 9.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1948".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 580 of Meeus index or 1533 from Brown series.
The length of this lunation is 29 days, 12 hours and 49 minutes and it is 2 hours and 16 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 5 minutes longer than the mean synodic month length. It is 6 hours and 58 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 ∠35.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠60.8°.
10 days since point of perigee on 25 November 2046 at 18:09 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 7 December 2046 at 12:36 in ♈ Aries.
The Moon is 404 691 km (251 463 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 833 km (251 552 mi).
4 days after ascending node on 1 December 2046 at 12:55 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 16 December 2046 at 00:01 in ♌ Leo.
7 days since the last southern standstill on 28 November 2046 at 22:56 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.048° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠26.034° at the point of next northern standstill on 13 December 2046 at 08:12 in ♊ Gemini.
4 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.
In 6 days on 13 December 2046 at 09:55 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.
