Quarter ♐ Sagittarius
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 51% and growing larger. The 7 days young Moon is in ♏ Scorpio.
* The exact date and time of this First Quarter phase is on 14 August 2013 at 10:56 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠22° of ♏ Scorpio tropical zodiac sector.
Lunar disc appears visually 2.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1944" and ∠1894".
Next Full Moon is the Sturgeon Moon of August 2013 after 6 days on 21 August 2013 at 01:45.
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 168 of Meeus index or 1121 from Brown series.
The length of the lunation is 29 days, 13 hours and 45 minutes. It is 47 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 1 hour and 1 minute longer than the mean synodic month length. It is 6 hours and 2 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠216.9°. At the beginning of next synodic month the true anomaly is going to be ∠249.2°.
11 days after point of apogee on 3 August 2013 at 08:53 in ♋ Cancer. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next perigee on 19 August 2013 at 01:26 in ♑ Capricorn.
The Moon is 368 796 km (229 159 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 362 265 km (225 101 mi).
1 day after ascending node on 13 August 2013 at 16:20 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 11 days, until the lunar orbit crosses from North to South in descending node on 26 August 2013 at 08:19 in ♉ Taurus.
1 day since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the beginning to the first part of the cycle.
12 days since the previous standstill on 2 August 2013 at 09:24 in ♊ Gemini when the Moon has reached North declination of ∠20.025°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-19.906° at the point of next southern standstill on 16 August 2013 at 12:06 in ♐ Sagittarius.
In 6 days on 21 August 2013 at 01:45 in ♒ Aquarius 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.
