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 22 January 2090 at 18:38 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 leaving the last ∠1° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.
Next Full Moon is the Snow Moon of February 2090 after 23 days on 14 February 2090 at 13:39.
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 1.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1920" and ∠1949".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1113 of Meeus index or 2066 from Brown series.
The length of this lunation is 29 days, 18 hours and 37 minutes and it is 35 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 5 hours and 53 minutes longer than the mean synodic month length. It is 1 hour and 10 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 ∠135.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠163.9°.
5 days since point of perigee on 17 January 2090 at 04:55 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 9 days until the Moon reaches the point of next apogee on 1 February 2090 at 09:55 in ♓ Pisces.
The Moon is 373 329 km (231 976 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 433 km (252 546 mi).
1 day after ascending node on 20 January 2090 at 12:25 in ♎ Libra the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 3 February 2090 at 19:04 in ♓ Pisces.
8 days since the last northern standstill on 14 January 2090 at 07:41 in ♊ Gemini when the Moon has reached North declination of ∠18.390° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-18.339° at the point of next southern standstill on 27 January 2090 at 04:34 in ♐ Sagittarius.
1 day since the beginning of this draconic month in ♎ Libra the Moon is navigating from the beginning to the first part of the lunar cycle.
In 8 days on 30 January 2090 at 14:34 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.
