Waning Crescent on . The illuminated surface of the moon is 16% and getting smaller. The lunar cycle is 25 days old.
The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Main moon phases of the following lunar cycle.
Moon is passing about ∠6° of ♌ Leo tropical zodiac sector.
Previous main lunar phase is the Last Quarter before 3 days on 13 September 2017 at 06:25.
Next Full Moon is the Hunter Moon of October 2017 after 19 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.
Lunar disc appears visually 1.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1945" and ∠1909".
The Moon is 25 days old and navigating from the second to the final 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°.
2 days since point of perigee on 13 September 2017 at 16:04 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 27 September 2017 at 06:49 in ♐ Sagittarius.
The Moon is 368 452 km (228 945 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 404 342 km (251 246 mi).
11 days after descending node on 4 September 2017 at 18:41 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 17 September 2017 at 18:28 in ♌ Leo.
1 day since the last northern standstill on 14 September 2017 at 13:00 in ♋ Cancer when the Moon has reached North declination of ∠19.438° the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-19.516° at the point of next southern standstill on 28 September 2017 at 10:06 in ♑ Capricorn.
26 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 3 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.
