First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 54% and growing larger. The 8 days young Moon is in ♎ Libra.
* The exact date and time of this First Quarter phase is on 16 July 2013 at 03:18 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 1.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1913" and ∠1888".
Next Full Moon is the Buck Moon of July 2013 after 6 days on 22 July 2013 at 18:15.
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 167 of Meeus index or 1120 from Brown series.
Length of current 167 lunation is 29 days, 14 hours and 36 minutes. It is 51 minutes longer than next lunation 168 length.
Length of current synodic month is 1 hour and 52 minutes longer than the mean length of synodic month, but it is still 5 hours and 11 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠191.6°. At the beginning of next synodic month true anomaly will be ∠216.9°. 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°).
9 days after point of apogee on 7 July 2013 at 00:36 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 21 July 2013 at 20:27 in ♑ Capricorn.
Moon is 374 626 km (232 782 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 358 402 km (222 701 mi).
13 days after its descending node on 3 July 2013 at 04:15 in ♉ Taurus, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 17 July 2013 at 14:58 in ♏ Scorpio.
26 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.
10 days after previous North standstill on 6 July 2013 at 02:09 in ♊ Gemini, when Moon has reached northern declination of ∠20.170°. Next 3 days the lunar orbit moves southward to face South declination of ∠-20.097° in the next southern standstill on 20 July 2013 at 03:12 in ♐ Sagittarius.
After 6 days on 22 July 2013 at 18:15 in ♑ Capricorn, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
