First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 48% and growing larger. The 7 days young Moon is in ♓ Pisces.
* The exact date and time of this First Quarter phase is on 9 December 2013 at 15:12 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠16° of ♓ Pisces tropical zodiac sector.
Lunar disc appears visually 1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1929" and ∠1948".
Next Full Moon is the Cold Moon of December 2013 after 7 days on 17 December 2013 at 09:28.
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.
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 172 of Meeus index or 1125 from Brown series.
Length of current 172 lunation is 29 days, 10 hours and 52 minutes. This is the year's shortest synodic month of 2013. It is 28 minutes longer than next lunation 173 length.
Length of current synodic month is 1 hour and 52 minutes shorter than the mean length of synodic month, but it is still 4 hours and 17 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠336.4°. At the beginning of next synodic month true anomaly will be ∠353°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
5 days after point of perigee on 4 December 2013 at 10:15 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 10 days, until it get to the point of next apogee on 19 December 2013 at 23:49 in ♋ Cancer.
Moon is 371 558 km (230 875 mi) away from Earth on this date. Moon moves farther next 10 days until apogee, when Earth-Moon distance will reach 406 269 km (252 444 mi).
8 days after its ascending node on 30 November 2013 at 16:59 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 3 days, until it will cross the ecliptic from North to South in descending node on 13 December 2013 at 10:10 in ♉ Taurus.
8 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
5 days after previous South standstill on 3 December 2013 at 16:38 in ♐ Sagittarius, when Moon has reached southern declination of ∠-19.552°. Next 7 days the lunar orbit moves northward to face North declination of ∠19.570° in the next northern standstill on 17 December 2013 at 01:00 in ♊ Gemini.
After 7 days on 17 December 2013 at 09:28 in ♊ Gemini, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
