Quarter ♎ Libra
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 ♍ Virgo.
* The exact date and time of this First Quarter phase is on 16 June 2013 at 17:24 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠23° of ♍ Virgo tropical zodiac sector.
Lunar disc appears visually 1.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1855" and ∠1889".
Next Full Moon is the Strawberry Moon of June 2013 after 6 days on 23 June 2013 at 11:32.
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 166 of Meeus index or 1119 from Brown series.
The length of the lunation is 29 days, 15 hours and 18 minutes. It is 42 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 2 hours and 34 minutes longer than the mean synodic month length. It is 4 hours and 29 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠168.8°. At the beginning of next synodic month the true anomaly is going to be ∠191.6°.
6 days after point of apogee on 9 June 2013 at 21:40 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next perigee on 23 June 2013 at 11:09 in ♑ Capricorn.
The Moon is 386 307 km (240 040 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 356 990 km (221 823 mi).
10 days after descending node on 6 June 2013 at 00:59 in ♉ Taurus. The Moon is located south of the ecliptic over the following 3 days, until the lunar orbit crosses from South to North in ascending node on 20 June 2013 at 09:51 in ♏ Scorpio.
23 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the second to the final part of the cycle.
7 days since the previous standstill on 8 June 2013 at 19:16 in ♊ Gemini when the Moon has reached North declination of ∠20.200°, the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-20.186° at the point of next southern standstill on 22 June 2013 at 16:11 in ♐ Sagittarius.
In 6 days on 23 June 2013 at 11:32 in ♑ Capricorn 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.
