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 18 November 2011 at 15:09 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 ∠24° of ♌ Leo tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2011 after 22 days on 10 December 2011 at 14:36.
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 1.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1918" and ∠1941".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 146 of Meeus index or 1099 from Brown series.
The length of this lunation is 29 days, 10 hours and 14 minutes and it is 1 hour and 43 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 2 hours and 30 minutes shorter than the mean synodic month length. It is 3 hours and 39 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 ∠5.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠21.6°.
9 days since point of apogee on 8 November 2011 at 13:20 in ♈ Aries 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 November 2011 at 23:24 in ♏ Scorpio.
The Moon is 373 633 km (232 165 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 359 692 km (223 502 mi).
5 days after descending node on 13 November 2011 at 00:35 in ♊ Gemini 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 26 November 2011 at 01:02 in ♐ Sagittarius.
5 days since the last northern standstill on 13 November 2011 at 07:23 in ♊ Gemini when the Moon has reached North declination of ∠22.558° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-22.552° at the point of next southern standstill on 26 November 2011 at 06:47 in ♐ Sagittarius.
19 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 25 November 2011 at 06:10 in ♐ Sagittarius 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.
