Gibbous ♑ Capricorn
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 ♑ Capricorn.
* The exact date and time of this First Quarter phase is on 12 September 2013 at 17:08 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 ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 3.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1907".
Next Full Moon is the Harvest Moon of September 2013 after 5 days on 19 September 2013 at 11:13.
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 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 169 of Meeus index or 1122 from Brown series.
Length of current 169 lunation is 29 days, 12 hours and 58 minutes. It is 43 minutes longer than next lunation 170 length.
Length of current synodic month is 14 minutes longer than the mean length of synodic month, but it is still 6 hours and 49 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠249.2°. At the beginning of next synodic month true anomaly will be ∠285.3°. 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°).
13 days after point of apogee on 30 August 2013 at 23:46 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 2 days, until it get to the point of next perigee on 15 September 2013 at 16:34 in ♑ Capricorn.
Moon is 363 522 km (225 882 mi) away from Earth on this date. Moon moves closer next 2 days until perigee, when Earth-Moon distance will reach 367 388 km (228 284 mi).
3 days after its ascending node on 9 September 2013 at 17:29 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 9 days, until it will cross the ecliptic from North to South in descending node on 22 September 2013 at 13:48 in ♉ Taurus.
3 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
1 day after previous South standstill on 12 September 2013 at 18:30 in ♐ Sagittarius, when Moon has reached southern declination of ∠-19.685°. Next 12 days the lunar orbit moves northward to face North declination of ∠19.599° in the next northern standstill on 26 September 2013 at 01:03 in ♊ Gemini.
After 5 days on 19 September 2013 at 11:13 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
