Last Quarter on . The illuminated surface of the moon is 54% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 10 November 2017 at 20:37 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 ∠14° of ♌ Leo tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2017 after 23 days on 3 December 2017 at 15:47.
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 0.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1945" and ∠1938".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 220 of Meeus index or 1173 from Brown series.
The length of this lunation is 29 days, 16 hours and 30 minutes and it is 2 hours and 18 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 3 hours and 46 minutes longer than the mean synodic month length. It is 3 hours and 17 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠114.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠147°.
4 days since point of perigee on 6 November 2017 at 00:09 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 21 November 2017 at 18:52 in ♐ Sagittarius.
The Moon is 368 549 km (229 006 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 406 132 km (252 359 mi).
Moon is in ascending node in ♌ Leo at 22:40 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 14 days until Moon's next descending node later on 25 November 2017 at 08:22 in ♒ Aquarius.
2 days since the last northern standstill on 8 November 2017 at 01:28 in ♋ Cancer when the Moon has reached North declination of ∠19.848° the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-19.959° at the point of next southern standstill on 22 November 2017 at 02:06 in ♑ Capricorn.
At 22:40 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.
In 7 days on 18 November 2017 at 11:42 in ♏ Scorpio 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.
