Last Quarter on . The illuminated surface of the moon is 42% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 16 July 2017 at 19:26 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 first ∠4° of ♉ Taurus tropical zodiac sector.
Next Full Moon is the Sturgeon Moon of August 2017 after 21 days on 7 August 2017 at 18:11.
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% wider than solar disc. Moon and Sun apparent angular diameters are ∠1946" and ∠1888".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 216 of Meeus index or 1169 from Brown series.
The length of this lunation is 29 days, 7 hours and 15 minutes and it is 1 hour and 30 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 5 hours and 29 minutes shorter than the mean synodic month length. It is 40 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 ∠11° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠27.9°.
11 days since point of apogee on 6 July 2017 at 04:27 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next perigee on 21 July 2017 at 17:09 in ♊ Gemini.
The Moon is 368 358 km (228 887 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 361 238 km (224 463 mi).
5 days after descending node on 12 July 2017 at 05:17 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 25 July 2017 at 00:46 in ♍ Virgo.
9 days since the last southern standstill on 8 July 2017 at 10:49 in ♑ Capricorn when the Moon has reached South declination of ∠-19.440° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠19.413° at the point of next northern standstill on 21 July 2017 at 22:11 in ♋ Cancer.
19 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.
In 5 days on 23 July 2017 at 09:46 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.
