Last Quarter on . The illuminated surface of the moon is 55% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 10 December 2066 at 00:38 UTC.
The moon rises at midnight and sets at noon. It is visible to the south in the morning.

Main moon phases of the following lunar cycle.
Moon is passing about ∠12° of ♍ Virgo tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2066 after 22 days on 31 December 2066 at 14:41.
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 7.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1811" and ∠1948".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 827 of Meeus index or 1780 from Brown series.
The length of this lunation is 29 days, 11 hours and 12 minutes and it is 13 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 1 hour and 32 minutes shorter than the mean synodic month length. It is 4 hours and 37 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 ∠328.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠346.7°.
4 days since point of apogee on 5 December 2066 at 07:41 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 16 days until the Moon reaches the point of next perigee on 26 December 2066 at 09:01 in ♉ Taurus.
The Moon is 395 821 km (245 952 mi) away from Earth and getting closer over the next 16 days until the point perigee when Earth-Moon distance is going to be 358 544 km (222 789 mi).
6 days after descending node on 3 December 2066 at 11:04 in ♊ Gemini the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 17 December 2066 at 07:22 in ♐ Sagittarius.
6 days since the last northern standstill on 2 December 2066 at 12:20 in ♊ Gemini when the Moon has reached North declination of ∠23.924° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-23.934° at the point of next southern standstill on 16 December 2066 at 13:29 in ♐ Sagittarius.
19 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final part of the lunar cycle.
In 7 days on 17 December 2066 at 00:17 in ♑ Capricorn the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
