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 29 August 2040 at 11:16 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 ∠7° of ♊ Gemini tropical zodiac sector.
Next Full Moon is the Harvest Moon of September 2040 after 22 days on 20 September 2040 at 17:43.
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 5.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1805" and ∠1901".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 502 of Meeus index or 1455 from Brown series.
The length of this lunation is 29 days, 14 hours and 47 minutes and it is 35 minutes longer than the upcoming lunation's length. 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 2 hours and 3 minutes longer than the mean synodic month length. It is 5 hours 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 ∠199° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠226.5°.
8 days since point of perigee on 21 August 2040 at 03:58 in ♒ Aquarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next apogee on 2 September 2040 at 10:15 in ♋ Cancer.
The Moon is 397 173 km (246 792 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 405 547 km (251 995 mi).
1 day after ascending node on 28 August 2040 at 19:18 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from North to South in descending node on 12 September 2040 at 06:11 in ♏ Scorpio.
10 days since the last southern standstill on 18 August 2040 at 23:35 in ♑ Capricorn when the Moon has reached South declination of ∠-26.313° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠26.397° at the point of next northern standstill on 1 September 2040 at 03:14 in ♋ Cancer.
1 day since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first part of the lunar cycle.
In 8 days on 6 September 2040 at 15:13 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.
