First Quarter on . The illuminated surface of the moon is 64% and growing larger. The lunar cycle is 9 days young.
* The exact date and time of this First Quarter phase is on 10 November 2013 at 05:57 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 passing about ∠5° of ♓ Pisces tropical zodiac sector.
Next Full Moon is the Beaver Moon of November 2013 after 6 days on 17 November 2013 at 15:16.
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% wider than solar disc. Moon and Sun apparent angular diameters are ∠1939" and ∠1938".
The Moon is 9 days young and navigating through the first part of the current synodic month. This is lunation 171 of Meeus index or 1124 from Brown series.
The length of this lunation is 29 days, 11 hours and 32 minutes and it is 40 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 1 hour and 12 minutes shorter than the mean synodic month length. It is 4 hours and 57 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 ∠315° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠336.4°.
5 days since point of perigee on 6 November 2013 at 09:28 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 22 November 2013 at 09:50 in ♋ Cancer.
The Moon is 369 730 km (229 740 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 446 km (251 932 mi).
8 days after ascending node on 3 November 2013 at 06:52 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from North to South in descending node on 16 November 2013 at 05:30 in ♉ Taurus.
5 days since the last southern standstill on 6 November 2013 at 06:43 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.511° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠19.534° at the point of next northern standstill on 19 November 2013 at 17:18 in ♊ Gemini.
8 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 6 days on 17 November 2013 at 15:16 in ♉ Taurus 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.
