Waning Gibbous on . The illuminated surface of the moon is 98% and getting smaller. The lunar cycle is 16 days old.
The 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.

Main moon phases of the following lunar cycle.
Moon is passing first ∠0° of ♓ Pisces tropical zodiac sector.
Previous main lunar phase is the Full Moon before 1 day on 6 September 2017 at 07:03.
Next Full Moon is the Hunter Moon of October 2017 after 28 days on 5 October 2017 at 18:40.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunar disc appears visually 1.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1883" and ∠1904".
The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 218 of Meeus index or 1171 from Brown series.
The length of this lunation is 29 days, 11 hours and 1 minute and it is 2 hours and 42 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 1 hour and 44 minutes shorter than the mean synodic month length. It is 4 hours and 25 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠49.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠79°.
8 days since point of apogee on 30 August 2017 at 11:25 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 13 September 2017 at 16:04 in ♊ Gemini.
The Moon is 380 602 km (236 495 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 369 856 km (229 818 mi).
2 days after descending node on 4 September 2017 at 18:41 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 17 September 2017 at 18:28 in ♌ Leo.
6 days since the last southern standstill on 1 September 2017 at 02:03 in ♑ Capricorn when the Moon has reached South declination of ∠-19.393° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠19.438° at the point of next northern standstill on 14 September 2017 at 13:00 in ♋ Cancer.
17 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.
In 12 days on 20 September 2017 at 05:30 in ♍ Virgo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
