Waning Gibbous on . The illuminated surface of the moon is 60% and getting smaller. The lunar cycle is 21 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 ♊ Gemini tropical zodiac sector.
Previous main lunar phase is the Full Moon before 5 days on 29 August 2015 at 18:35.
Next Full Moon is the Harvest Moon of September 2015 after 23 days on 28 September 2015 at 02:50.
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 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1923" and ∠1903".
The Moon is 21 days old and navigating from the middle to the last part of the current synodic month. This is lunation 193 of Meeus index or 1146 from Brown series.
The length of this lunation is 29 days, 15 hours and 48 minutes and it is 1 hour and 36 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 4 minutes longer than the mean synodic month length. It is 3 hours and 59 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠144.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠169.3°.
4 days since point of perigee on 30 August 2015 at 15:24 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next apogee on 14 September 2015 at 11:28 in ♎ Libra.
The Moon is 372 667 km (231 565 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 466 km (252 566 mi).
4 days after descending node on 31 August 2015 at 10:16 in ♈ Aries the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 14 September 2015 at 04:38 in ♎ Libra.
10 days since the last southern standstill on 25 August 2015 at 03:44 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.206° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠18.163° at the point of next northern standstill on 6 September 2015 at 17:06 in ♊ Gemini.
17 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 8 days on 13 September 2015 at 06:41 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.
