Last Quarter on . The illuminated surface of the moon is 58% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 23 December 2081 at 03:55 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 ∠23° of ♍ Virgo tropical zodiac sector.
Next Full Moon is the Wolf Moon of January 2082 after 23 days on 14 January 2082 at 18:11.
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 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1951".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1013 of Meeus index or 1966 from Brown series.
The length of this lunation is 29 days, 13 hours and 52 minutes and it is 2 hours and 26 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 8 minutes longer than the mean synodic month length. It is 5 hours and 55 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 ∠52.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠84.8°.
Moon is at perigee at 10:49 about 13 days since last apogee on 9 December 2081 at 00:48 in ♈ Aries the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 14 days until point of next apogee on 5 January 2082 at 22:19 in ♓ Pisces.
This perigee Moon is 370 264 km (230 071 mi) away from Earth. This is the year's farthest perigee of 2081. It is 7 756 km closer than the mean perigee distance, but it is still 92 km further than the closest perigee of 21st century.
1 day after descending node on 21 December 2081 at 12:04 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 January 2082 at 19:51 in ♓ Pisces.
6 days since the last northern standstill on 16 December 2081 at 08:03 in ♊ Gemini when the Moon has reached North declination of ∠28.126° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-28.138° at the point of next southern standstill on 29 December 2081 at 05:56 in ♐ Sagittarius.
14 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.
In 7 days on 30 December 2081 at 04:28 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.
