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 17 June 2017 at 11:33 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 ∠3° of ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.
Next Full Moon is the Buck Moon of July 2017 after 21 days on 9 July 2017 at 04:07.
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 0.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1893" and ∠1888".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 215 of Meeus index or 1168 from Brown series.
The length of this lunation is 29 days, 6 hours and 46 minutes and it is 29 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2017. 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 58 minutes shorter than the mean synodic month length. It is 11 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° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠11°.
8 days since point of apogee on 8 June 2017 at 22:21 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 23 June 2017 at 10:49 in ♊ Gemini.
The Moon is 378 552 km (235 221 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 357 938 km (222 412 mi).
2 days after descending node on 15 June 2017 at 02:40 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 27 June 2017 at 16:26 in ♌ Leo.
6 days since the last southern standstill on 11 June 2017 at 03:36 in ♑ Capricorn when the Moon has reached South declination of ∠-19.428° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠19.434° at the point of next northern standstill on 24 June 2017 at 11:12 in ♋ Cancer.
17 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 6 days on 24 June 2017 at 02:31 in ♋ Cancer 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.
