* The exact date and time of this First Quarter phase is on 28 September 2017 at 02:54 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠10° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 7.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1915".
Next Full Moon is the Hunter Moon of October 2017 after 7 days on 5 October 2017 at 18:40.
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 219 of Meeus index or 1172 from Brown series.
Length of current 219 lunation is 29 days, 13 hours and 42 minutes. It is 2 hours and 48 minutes shorter than next lunation 220 length.
Length of current synodic month is 58 minutes longer than the mean length of synodic month, but it is still 6 hours and 5 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠79°. At beginning of next synodic month true anomaly will be ∠114.6°. 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°).
1 day after point of apogee on 27 September 2017 at 06:49 in ♐ Sagittarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 9 October 2017 at 05:51 in ♊ Gemini.

10 days after its ascending node on 17 September 2017 at 18:28 in ♌ Leo, 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 2 October 2017 at 02:05 in ♒ Aquarius.
10 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the beginning to the first part of it.
At 10:06 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-19.516°. Next 13 days the lunar orbit will move in opposite northward direction to face North declination of ∠19.616° in its northern standstill point on 11 October 2017 at 18:21 in ♋ Cancer.
After 7 days on 5 October 2017 at 18:40 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
