* 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.
Length of current 135 lunation is 29 days, 15 hours and 27 minutes. It is 2 hours and 1 minute shorter than next lunation 136 length.
Length of current synodic month is 2 hours and 43 minutes longer than the mean length of synodic month, but it is still 4 hours and 20 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠67°. At beginning of next synodic month true anomaly will be ∠103.5°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
1 day after point of apogee on 13 December 2010 at 08:34 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 11 days, until it get to the point of next perigee on 25 December 2010 at 12:24 in ♌ Leo.
Moon is 404 842 km (251 557 mi) away from Earth on this date. Moon moves closer next 11 days until perigee, when Earth-Moon distance will reach 368 463 km (228 952 mi).
7 days after its ascending node on 7 December 2010 at 04:15 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 7 days, until it will cross the ecliptic from North to South in descending node on 21 December 2010 at 14:08 in ♊ Gemini.

8 days after previous South standstill on 6 December 2010 at 02:10 in ♐ Sagittarius, when Moon has reached southern declination of ∠-24.233°. Next 6 days the lunar orbit moves northward to face North declination of ∠24.238° in the next northern standstill on 20 December 2010 at 12:37 in ♊ Gemini.
After 6 days on 21 December 2010 at 08:13 in ♊ Gemini, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
