Gibbous ♎ Libra
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 58% and growing larger. The 8 days young Moon is in ♎ Libra.
* 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 ∠6° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 0.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1879" and ∠1888".
Next Full Moon is the Strawberry Moon of June 2013 after 5 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 8 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.
Length of current 166 lunation is 29 days, 15 hours and 18 minutes. It is 42 minutes longer than next lunation 167 length.
Length of current synodic month is 2 hours and 34 minutes longer than the mean length of synodic month, but it is still 4 hours and 29 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠168.8°. At the beginning of next synodic month true anomaly will be ∠191.6°. 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°).
7 days after point of apogee on 9 June 2013 at 21:40 in ♊ Gemini. 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 23 June 2013 at 11:09 in ♑ Capricorn.
Moon is 381 436 km (237 013 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 356 990 km (221 823 mi).
11 days after its descending node on 6 June 2013 at 00:59 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 2 days, until it will cross the ecliptic from South to North in ascending node on 20 June 2013 at 09:51 in ♏ Scorpio.
24 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.
8 days after previous North standstill on 8 June 2013 at 19:16 in ♊ Gemini, when Moon has reached northern declination of ∠20.200°. Next 5 days the lunar orbit moves southward to face South declination of ∠-20.186° in the next southern standstill on 22 June 2013 at 16:11 in ♐ Sagittarius.
After 5 days on 23 June 2013 at 11:32 in ♑ Capricorn, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
