Gibbous ♈ Aries
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 59% and growing larger. The 8 days young Moon is in ♈ Aries.
* The exact date and time of this First Quarter phase is on 13 December 2010 at 13:59 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing first ∠2° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 9.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1949".
Next Full Moon is the Cold Moon of December 2010 after 6 days on 21 December 2010 at 08:13.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 135 of Meeus index or 1088 from Brown series.
The length of the lunation is 29 days, 15 hours and 27 minutes. It is 2 hours and 1 minute shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the 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 43 minutes longer than the mean synodic month length. It is 4 hours and 20 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠67°. At the beginning of next synodic month the true anomaly is going to be ∠103.5°.
1 day after point of apogee on 13 December 2010 at 08:34 in ♓ Pisces. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next perigee on 25 December 2010 at 12:24 in ♌ Leo.
The Moon is 404 842 km (251 557 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 368 463 km (228 952 mi).
7 days after ascending node on 7 December 2010 at 04:15 in ♑ Capricorn. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 21 December 2010 at 14:08 in ♊ Gemini.
7 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the beginning to the first part of the cycle.
8 days since the previous standstill on 6 December 2010 at 02:10 in ♐ Sagittarius when the Moon has reached South declination of ∠-24.233°, the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠24.238° at the point of next northern standstill on 20 December 2010 at 12:37 in ♊ Gemini.
In 6 days on 21 December 2010 at 08:13 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.
