Waxing Crescent on . The illuminated surface of the moon is 1% and growing larger. The lunar cycle is 1 day young.
The moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Main moon phases of the following lunar cycle.
Moon is passing about ∠9° of ♍ Virgo tropical zodiac sector.
Previous main lunar phase is the New Moon before 1 day on 21 August 2017 at 18:30.
Next Full Moon is the Harvest Moon of September 2017 after 14 days on 6 September 2017 at 07:03.
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 0.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1892" and ∠1897".
The Moon is 1 day young and navigating from the beginning to the first 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°.
3 days 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 7 days until the Moon reaches the point of next apogee on 30 August 2017 at 11:25 in ♐ Sagittarius.
The Moon is 378 902 km (235 439 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 404 307 km (251 225 mi).
1 day after ascending node on 21 August 2017 at 10:34 in ♌ Leo the Moon is positioned north of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from North to South in descending node on 4 September 2017 at 18:41 in ♒ Aquarius.
4 days 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 9 days to face maximum declination of ∠-19.393° at the point of next southern standstill on 1 September 2017 at 02:03 in ♑ Capricorn.
1 day since the beginning of this draconic month in ♌ Leo the Moon is navigating from the beginning to the first part of the lunar cycle.
In 14 days on 6 September 2017 at 07:03 in ♓ Pisces the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
