Quarter ♐ Sagittarius
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 49% and growing larger. The 7 days young Moon is in ♐ Sagittarius.
* The exact date and time of this First Quarter phase is on 24 August 2012 at 13:54 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing first ∠1° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 3.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1898".
Next Full Moon is the Sturgeon Moon of August 2012 after 7 days on 31 August 2012 at 13:58.
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 156 of Meeus index or 1109 from Brown series.
Length of current 156 lunation is 29 days, 10 hours and 16 minutes. It is 24 minutes longer than next lunation 157 length.
Length of current synodic month is 2 hours and 28 minutes shorter than the mean length of synodic month, but it is still 3 hours and 41 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠283.7°. At the beginning of next synodic month true anomaly will be ∠312.9°. 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°).
1 day after point of perigee on 23 August 2012 at 19:39 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 13 days, until it get to the point of next apogee on 7 September 2012 at 06:00 in ♊ Gemini.
Moon is 363 323 km (225 758 mi) away from Earth on this date. Moon moves farther next 13 days until apogee, when Earth-Moon distance will reach 404 296 km (251 218 mi).
Moon is in ascending node in ♐ Sagittarius at 11:38 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 13 days to meet descending node on 7 September 2012 at 02:08 in ♉ Taurus.
At 11:38 on this date the Moon is completing its previous draconic month and is entering the new one.
12 days after previous North standstill on 12 August 2012 at 09:47 in ♊ Gemini, when Moon has reached northern declination of ∠21.492°. Next day the lunar orbit moves southward to face South declination of ∠-21.379° in the next southern standstill on 25 August 2012 at 18:40 in ♐ Sagittarius.
After 7 days on 31 August 2012 at 13:58 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
