First Quarter on . The illuminated surface of the moon is 49% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 20 November 2012 at 14:31 UTC.
The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Main moon phases of the following lunar cycle.
Moon is leaving the last ∠3° of ♒ Aquarius tropical zodiac sector and will enter ♓ Pisces later.
Next Full Moon is the Beaver Moon of November 2012 after 8 days on 28 November 2012 at 14:46.
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 2.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1889" and ∠1942".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 159 of Meeus index or 1112 from Brown series.
The length of this lunation is 29 days, 10 hours and 34 minutes and it is 28 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 10 minutes shorter than the mean synodic month length. It is 3 hours and 59 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 ∠351.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠6.8°.
6 days since point of perigee on 14 November 2012 at 10:21 in ♏ Scorpio the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next apogee on 28 November 2012 at 19:35 in ♊ Gemini.
The Moon is 379 468 km (235 790 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 406 366 km (252 504 mi).
6 days after ascending node on 14 November 2012 at 04:37 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 27 November 2012 at 17:05 in ♉ Taurus.
4 days since the last southern standstill on 15 November 2012 at 16:10 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.914° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠20.924° at the point of next northern standstill on 29 November 2012 at 14:33 in ♊ Gemini.
6 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first part of the lunar cycle.
In 8 days on 28 November 2012 at 14:46 in ♊ Gemini the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
