Last Quarter on . The illuminated surface of the moon is 50% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 18 August 2090 at 11:05 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 ∠3° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.
Next Full Moon is the Harvest Moon of September 2090 after 21 days on 8 September 2090 at 22:44.
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 3.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1828" and ∠1896".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1120 of Meeus index or 2073 from Brown series.
The length of this lunation is 29 days, 7 hours and 40 minutes and it is 24 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2090. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 5 hours and 4 minutes shorter than the mean synodic month length. It is 1 hour and 5 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 ∠331.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠348.5°.
5 days since point of apogee on 13 August 2090 at 08:23 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 26 August 2090 at 01:13 in ♍ Virgo.
The Moon is 392 105 km (243 643 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 358 032 km (222 471 mi).
5 days after descending node on 13 August 2090 at 01:17 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 26 August 2090 at 13:58 in ♍ Virgo.
11 days since the last southern standstill on 6 August 2090 at 13:57 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.326° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠18.266° at the point of next northern standstill on 21 August 2090 at 05:49 in ♋ Cancer.
19 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 25 August 2090 at 08:58 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.
