Gibbous ♒ Aquarius
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 57% and growing larger. The 8 days young Moon is in ♒ Aquarius.
* The exact date and time of this First Quarter phase is on 20 October 2015 at 20:31 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 ♒ Aquarius tropical zodiac sector.
Lunar disc appears visually 0.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1922" and ∠1928".
Next Full Moon is the Hunter Moon of October 2015 after 6 days on 27 October 2015 at 12:05.
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 195 of Meeus index or 1148 from Brown series.
Length of current 195 lunation is 29 days, 17 hours and 41 minutes. This is the year's longest synodic month of 2015. It is 59 minutes longer than next lunation 196 length.
Length of current synodic month is 4 hours and 57 minutes longer than the mean length of synodic month, but it is still 2 hours and 6 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠192.9°. At the beginning of next synodic month true anomaly will be ∠220.3°. 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 11 October 2015 at 13:17 in ♍ Virgo. 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 26 October 2015 at 12:59 in ♈ Aries.
Moon is 372 933 km (231 730 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 358 464 km (222 739 mi).
10 days after its ascending node on 11 October 2015 at 10:54 in ♎ Libra, the Moon is following the northern part of its orbit for the next 3 days, until it will cross the ecliptic from North to South in descending node on 25 October 2015 at 07:37 in ♈ Aries.
10 days after beginning of current draconic month in ♎ Libra, the Moon is moving from the beginning to the first part of it.
2 days after previous South standstill on 18 October 2015 at 18:31 in ♐ Sagittarius, when Moon has reached southern declination of ∠-18.190°. Next 9 days the lunar orbit moves northward to face North declination of ∠18.241° in the next northern standstill on 31 October 2015 at 09:02 in ♊ Gemini.
After 6 days on 27 October 2015 at 12:05 in ♉ Taurus, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
