First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 62% and growing larger. The 8 days young Moon is in ♑ Capricorn.
* The exact date and time of this First Quarter phase is on 21 September 2015 at 08:59 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠13° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 1.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1889" and ∠1912".
Next Full Moon is the Harvest Moon of September 2015 after 5 days on 28 September 2015 at 02:50.
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 194 of Meeus index or 1147 from Brown series.
Length of current 194 lunation is 29 days, 17 hours and 24 minutes. It is 17 minutes shorter than next lunation 195 length.
Length of current synodic month is 4 hours and 40 minutes longer than the mean length of synodic month, but it is still 2 hours and 23 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠169.3°. At the beginning of next synodic month true anomaly will be ∠192.9°. 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°).
8 days after point of apogee on 14 September 2015 at 11:28 in ♎ Libra. 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 28 September 2015 at 01:46 in ♈ Aries.
Moon is 379 419 km (235 760 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 356 877 km (221 753 mi).
8 days after its ascending node on 14 September 2015 at 04:38 in ♎ Libra, the Moon is following the northern part of its orbit for the next 5 days, until it will cross the ecliptic from North to South in descending node on 27 September 2015 at 21:04 in ♓ Pisces.
8 days after beginning of current draconic month in ♎ Libra, the Moon is moving from the beginning to the first part of it.
1 day after previous South standstill on 21 September 2015 at 12:02 in ♐ Sagittarius, when Moon has reached southern declination of ∠-18.134°. Next 11 days the lunar orbit moves northward to face North declination of ∠18.140° in the next northern standstill on 3 October 2015 at 23:55 in ♊ Gemini.
After 5 days on 28 September 2015 at 02:50 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
