First Quarter on . The illuminated surface of the moon is 51% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 6 December 2073 at 09:33 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 ∠16° of ♓ Pisces tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2073 after 8 days on 14 December 2073 at 13:49.
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% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1798" and ∠1948".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 914 of Meeus index or 1867 from Brown series.
The length of this lunation is 29 days, 11 hours and 43 minutes and it is 1 hour and 59 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 1 minute shorter than the mean synodic month length. It is 5 hours and 8 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 ∠22.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠43.1°.
8 days since point of perigee on 27 November 2073 at 21:03 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 9 December 2073 at 22:16 in ♈ Aries.
The Moon is 398 684 km (247 731 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 405 427 km (251 921 mi).
2 days after descending node on 3 December 2073 at 22:40 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 18 December 2073 at 11:14 in ♌ Leo.
5 days since the last southern standstill on 1 December 2073 at 10:11 in ♑ Capricorn when the Moon has reached South declination of ∠-20.206° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠20.261° at the point of next northern standstill on 15 December 2073 at 22:12 in ♋ Cancer.
15 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.
In 8 days on 14 December 2073 at 13:49 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.
