First Quarter on . The illuminated surface of the moon is 56% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 17 November 2007 at 22:32 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 first ∠3° of ♓ Pisces tropical zodiac sector.
Next Full Moon is the Beaver Moon of November 2007 after 6 days on 24 November 2007 at 14:30.
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 1.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1904" and ∠1941".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 97 of Meeus index or 1050 from Brown series.
The length of this lunation is 29 days, 18 hours and 37 minutes and it is 40 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2007. 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 5 hours and 53 minutes longer than the mean synodic month length. It is 1 hour and 10 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 ∠183.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠209.6°.
8 days since point of apogee on 9 November 2007 at 12:31 in ♏ Scorpio 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 24 November 2007 at 00:12 in ♊ Gemini.
The Moon is 376 366 km (233 863 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 357 196 km (221 951 mi).
Moon is in ascending node in ♓ Pisces at 12:46 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 12 days until Moon's next descending node later on 30 November 2007 at 23:09 in ♌ Leo.
5 days since the last southern standstill on 13 November 2007 at 04:37 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.006° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠27.958° at the point of next northern standstill on 26 November 2007 at 03:58 in ♊ Gemini.
At 12:46 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 6 days on 24 November 2007 at 14:30 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.
