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 22 September 2019 at 02:41 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 ∠21° of ♊ Gemini tropical zodiac sector.
Next Full Moon is the Hunter Moon of October 2019 after 22 days on 13 October 2019 at 21:08.
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 1.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1880" and ∠1911".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 243 of Meeus index or 1196 from Brown series.
The length of this lunation is 29 days, 7 hours and 49 minutes and it is 1 hour and 23 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 55 minutes shorter than the mean synodic month length. It is 1 hour and 14 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 ∠356.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠11.4°.
7 days since point of apogee on 13 September 2019 at 13:32 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 28 September 2019 at 02:27 in ♍ Virgo.
The Moon is 381 332 km (236 949 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 357 803 km (222 328 mi).
12 days after descending node on 8 September 2019 at 17:35 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 23 September 2019 at 06:30 in ♋ Cancer.
13 days since the last southern standstill on 8 September 2019 at 09:39 in ♑ Capricorn when the Moon has reached South declination of ∠-22.539° the lunar orbit is extending northward over the next day to face maximum declination of ∠22.681° at the point of next northern standstill on 23 September 2019 at 01:54 in ♋ Cancer.
25 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 7 days on 28 September 2019 at 18:26 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.
