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.
The length of the lunation is 29 days, 12 hours and 58 minutes. It is 43 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 14 minutes longer than the mean synodic month length. It is 6 hours and 49 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠249.2°. At the beginning of next synodic month the true anomaly is going to be ∠285.3°.
13 days after point of apogee on 30 August 2013 at 23:46 in ♋ Cancer. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next perigee on 15 September 2013 at 16:34 in ♑ Capricorn.
The Moon is 363 522 km (225 882 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 367 388 km (228 284 mi).
3 days after ascending node on 9 September 2013 at 17:29 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 9 days, until the lunar orbit crosses from North to South in descending node on 22 September 2013 at 13:48 in ♉ Taurus.
3 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the beginning to the first part of the cycle.
1 day since the previous standstill on 12 September 2013 at 18:30 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.685°, the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠19.599° at the point of next northern standstill on 26 September 2013 at 01:03 in ♊ Gemini.
In 5 days on 19 September 2013 at 11:13 in ♓ Pisces 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.
