Waning Crescent on . The illuminated surface of the moon is 7% and getting smaller. The lunar cycle is 27 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 leaving the last ∠4° of ♋ Cancer tropical zodiac sector and will enter ♌ Leo later.
Previous main lunar phase is the Last Quarter before 4 days on 15 August 2017 at 01:15.
Next Full Moon is the Harvest Moon of September 2017 after 17 days on 6 September 2017 at 07:03.
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 3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1953" and ∠1896".
The Moon is 27 days old and navigating from the second to the final part of the current synodic month. This is lunation 217 of Meeus index or 1170 from Brown series.
The length of this lunation is 29 days, 8 hours and 45 minutes and it is 2 hours and 15 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 3 hours and 59 minutes shorter than the mean synodic month length. It is 2 hours and 10 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 ∠27.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠49.5°.
1 day since point of perigee on 18 August 2017 at 13:14 in ♋ Cancer 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 30 August 2017 at 11:25 in ♐ Sagittarius.
The Moon is 366 952 km (228 013 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 404 307 km (251 225 mi).
11 days after descending node on 8 August 2017 at 10:56 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 21 August 2017 at 10:34 in ♌ Leo.
1 day since the last northern standstill on 18 August 2017 at 06:50 in ♋ Cancer when the Moon has reached North declination of ∠19.381° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-19.393° at the point of next southern standstill on 1 September 2017 at 02:03 in ♑ Capricorn.
25 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.
In 2 days on 21 August 2017 at 18:30 in ♌ Leo 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.
