Last Quarter on . The illuminated surface of the moon is 51% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 23 August 2019 at 14:56 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 ∠1° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.
Next Full Moon is the Harvest Moon of September 2019 after 21 days on 14 September 2019 at 04:33.
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 2.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1846" and ∠1898".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 242 of Meeus index or 1195 from Brown series.
The length of this lunation is 29 days, 7 hours and 25 minutes and it is 24 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2019. 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 19 minutes shorter than the mean synodic month length. It is 50 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 ∠340.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠356.3°.
6 days since point of apogee on 17 August 2019 at 10:50 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 30 August 2019 at 15:57 in ♍ Virgo.
The Moon is 388 331 km (241 298 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 357 177 km (221 939 mi).
10 days after descending node on 12 August 2019 at 14:45 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 27 August 2019 at 01:50 in ♋ Cancer.
11 days since the last southern standstill on 12 August 2019 at 04:28 in ♑ Capricorn when the Moon has reached South declination of ∠-22.399° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠22.473° at the point of next northern standstill on 26 August 2019 at 17:53 in ♋ Cancer.
23 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 30 August 2019 at 10:37 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.
