First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 47% and growing larger. The 7 days young Moon is in ♏ Scorpio.
* The exact date and time of this First Quarter phase is on 22 August 2015 at 19:31 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 4.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1813" and ∠1897".
Next Full Moon is the Sturgeon Moon of August 2015 after 7 days on 29 August 2015 at 18:35.
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 193 of Meeus index or 1146 from Brown series.
Length of current 193 lunation is 29 days, 15 hours and 48 minutes. It is 1 hour and 36 minutes shorter than next lunation 194 length.
Length of current synodic month is 3 hours and 4 minutes longer than the mean length of synodic month, but it is still 3 hours and 59 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠144.1°. At beginning of next synodic month true anomaly will be ∠169.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
4 days after point of apogee on 18 August 2015 at 02:33 in ♎ Libra. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 30 August 2015 at 15:24 in ♓ Pisces.
Moon is 395 375 km (245 675 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 358 289 km (222 630 mi).
4 days after its ascending node on 17 August 2015 at 23:05 in ♍ Virgo, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 31 August 2015 at 10:16 in ♈ Aries.
4 days after beginning of current draconic month in ♍ Virgo, the Moon is moving from the beginning to the first part of it.
12 days after previous North standstill on 10 August 2015 at 11:11 in ♊ Gemini, when Moon has reached northern declination of ∠18.288°. Next 2 days the lunar orbit moves southward to face South declination of ∠-18.206° in the next southern standstill on 25 August 2015 at 03:44 in ♐ Sagittarius.
After 7 days on 29 August 2015 at 18:35 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
