Last Quarter on . The illuminated surface of the moon is 51% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 3 January 2100 at 13:03 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 ∠13° of ♎ Libra tropical zodiac sector.
Next Full Moon is the Wolf Moon of January 2100 after 22 days on 26 January 2100 at 02:49.
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 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1951".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1236 of Meeus index or 2189 from Brown series.
The length of this lunation is 29 days, 13 hours and 47 minutes and it is 2 hours and 12 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 3 minutes longer than the mean synodic month length. It is 6 hours 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 ∠49.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠81.3°.
Moon is at perigee at 08:57 about 13 days since last apogee on 20 December 2099 at 13:16 in ♈ Aries the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 13 days until point of next apogee on 17 January 2100 at 10:48 in ♈ Aries.
This perigee Moon is 370 356 km (230 129 mi) away from Earth. This is the year's farthest perigee of 2100. It is 7 848 km closer than the mean perigee distance, but it is still 0 km further than the closest perigee of 21st century.
1 day after descending node on 1 January 2100 at 21:13 in ♍ Virgo 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 15 January 2100 at 03:56 in ♓ Pisces.
7 days since the last northern standstill on 26 December 2099 at 23:34 in ♊ Gemini when the Moon has reached North declination of ∠28.345° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-28.379° at the point of next southern standstill on 8 January 2100 at 21:59 in ♐ Sagittarius.
15 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 10 January 2100 at 12:55 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.
