Last Quarter on . The illuminated surface of the moon is 53% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 13 January 2099 at 17:26 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 ∠21° of ♎ Libra tropical zodiac sector.
Next Full Moon is the Snow Moon of February 2099 after 23 days on 5 February 2099 at 12:48.
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 0.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1940" and ∠1951".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1224 of Meeus index or 2177 from Brown series.
The length of this lunation is 29 days, 17 hours and 43 minutes and it is 1 hour and 15 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 4 hours and 59 minutes longer than the mean synodic month length. It is 2 hours and 4 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 ∠115.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠149°.
4 days since point of perigee on 8 January 2099 at 18:21 in ♌ Leo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 24 January 2099 at 12:47 in ♓ Pisces.
The Moon is 369 446 km (229 563 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 406 101 km (252 339 mi).
1 day after descending node on 12 January 2099 at 15:35 in ♎ Libra the Moon is positioned south of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from South to North in ascending node on 26 January 2099 at 21:58 in ♈ Aries.
7 days since the last northern standstill on 6 January 2099 at 00:46 in ♋ Cancer when the Moon has reached North declination of ∠28.354° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-28.389° at the point of next southern standstill on 18 January 2099 at 22:15 in ♐ Sagittarius.
13 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the second to the final part of the lunar cycle.
In 7 days on 21 January 2099 at 09:07 in ♒ Aquarius 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.
