Last Quarter on . The illuminated surface of the moon is 58% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 9 August 2099 at 07:14 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 ♉ Taurus tropical zodiac sector.
Next Full Moon is the Sturgeon Moon of August 2099 after 22 days on 30 August 2099 at 17:56.
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 5.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1793" and ∠1893".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1231 of Meeus index or 2184 from Brown series.
The length of this lunation is 29 days, 7 hours and 54 minutes and it is 2 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2099. 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 4 hours and 50 minutes shorter than the mean synodic month length. It is 1 hour and 19 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 ∠320.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠339.4°.
3 days since point of apogee on 5 August 2099 at 08:15 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 17 August 2099 at 14:24 in ♍ Virgo.
The Moon is 399 778 km (248 411 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 359 644 km (223 472 mi).
3 days after ascending node on 5 August 2099 at 03:00 in ♓ Pisces 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 18 August 2099 at 13:42 in ♍ Virgo.
10 days since the last southern standstill on 28 July 2099 at 23:58 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.504° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠28.579° at the point of next northern standstill on 12 August 2099 at 14:22 in ♊ Gemini.
3 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.
In 7 days on 16 August 2099 at 08:54 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.
