Waxing Gibbous on . The illuminated surface of the moon is 70% and growing larger. The lunar cycle is 9 days young.
The moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Main moon phases of the following lunar cycle.
Moon is passing first ∠2° of ♑ Capricorn tropical zodiac sector.
Previous main lunar phase is the First Quarter before 2 days on 29 August 2017 at 08:13.
Next Full Moon is the Harvest Moon of September 2017 after 5 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 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1901".
The Moon is 9 days young and navigating from the first to the middle 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°.
1 day 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 13 days until the Moon reaches the point of next perigee on 13 September 2017 at 16:04 in ♊ Gemini.
The Moon is 405 126 km (251 734 mi) away from Earth and getting closer over the next 13 days until the point perigee when Earth-Moon distance is going to be 369 856 km (229 818 mi).
10 days after ascending node on 21 August 2017 at 10:34 in ♌ Leo the Moon is positioned north of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from North to South in descending node on 4 September 2017 at 18:41 in ♒ Aquarius.
13 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 day to face maximum declination of ∠-19.393° at the point of next southern standstill on 1 September 2017 at 02:03 in ♑ Capricorn.
10 days 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 5 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.
