Last Quarter on . The illuminated surface of the moon is 56% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 20 August 2079 at 00:00 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 ∠20° of ♉ Taurus tropical zodiac sector.
Next Full Moon is the Harvest Moon of September 2079 after 22 days on 11 September 2079 at 05:36.
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 3.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1956" and ∠1896".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 984 of Meeus index or 1937 from Brown series.
The length of this lunation is 29 days, 8 hours and 29 minutes and it is 2 hours and 34 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 15 minutes shorter than the mean synodic month length. It is 1 hour and 54 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 ∠28.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠50.5°.
11 days since point of apogee on 7 August 2079 at 14:51 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 23 August 2079 at 09:43 in ♋ Cancer.
The Moon is 366 371 km (227 652 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 366 372 km (227 653 mi).
1 day after ascending node on 17 August 2079 at 13:43 in ♈ Aries the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 30 August 2079 at 09:11 in ♎ Libra.
10 days since the last southern standstill on 8 August 2079 at 23:04 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.063° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠28.160° at the point of next northern standstill on 22 August 2079 at 14:13 in ♊ Gemini.
1 day since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.
In 7 days on 26 August 2079 at 17:02 in ♌ Leo 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.
