Previous main lunar phase is the Full Moon before 6 days on 6 September 2017 at 07:03.
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Moon is passing about ∠10° of ♊ Gemini tropical zodiac sector.
Lunar disc appears visually 3.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1970" and ∠1907".
Next Full Moon is the Hunter Moon of October 2017 after 23 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 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 218 of Meeus index or 1171 from Brown series.
Length of current 218 lunation is 29 days, 11 hours and 1 minute. It is 2 hours and 42 minutes shorter than next lunation 219 length.
Length of current synodic month is 1 hour and 44 minutes shorter than the mean length of synodic month, but it is still 4 hours and 25 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠49.5°. At beginning of next synodic month true anomaly will be ∠79°. 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°).
13 days after point of apogee on 30 August 2017 at 11:25 in ♐ Sagittarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 13 September 2017 at 16:04 in ♊ Gemini.
Moon is 363 830 km (226 073 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 369 856 km (229 818 mi).
7 days after its descending node on 4 September 2017 at 18:41 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 5 days, until it will cross the ecliptic from South to North in ascending node on 17 September 2017 at 18:28 in ♌ Leo.
22 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the second to the final part of it.
11 days after previous South standstill on 1 September 2017 at 02:03 in ♑ Capricorn, when Moon has reached southern declination of ∠-19.393°. Next 2 days the lunar orbit moves northward to face North declination of ∠19.438° in the next northern standstill on 14 September 2017 at 13:00 in ♋ Cancer.
After 7 days on 20 September 2017 at 05:30 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
