Last Quarter on . The illuminated surface of the moon is 45% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 16 September 2090 at 23:48 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 first ∠1° of ♋ Cancer tropical zodiac sector.
Next Full Moon is the Hunter Moon of October 2090 after 21 days on 8 October 2090 at 15:54.
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 1.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1884" and ∠1910".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1121 of Meeus index or 2074 from Brown series.
The length of this lunation is 29 days, 8 hours and 4 minutes and it is 1 hour and 2 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 40 minutes shorter than the mean synodic month length. It is 1 hour and 29 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 ∠348.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠3.8°.
7 days since point of apogee on 9 September 2090 at 14:56 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 23 September 2090 at 11:39 in ♍ Virgo.
The Moon is 380 526 km (236 448 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 357 224 km (221 969 mi).
8 days after descending node on 9 September 2090 at 07:13 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 23 September 2090 at 00:57 in ♍ Virgo.
At 14:20 the Moon is meeting its standstill point to reach North declination of ∠18.226°. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-18.246° at the point of next southern standstill in ♑ Capricorn on 30 September 2090 at 02:41.
21 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 23 September 2090 at 17:03 in ♍ Virgo 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.
