Waxing Gibbous on . The illuminated surface of the moon is 77% and growing larger. The lunar cycle is 10 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 ∠4° of ♑ Capricorn tropical zodiac sector.
Previous main lunar phase is the First Quarter before 2 days on 22 August 2015 at 19:31.
Next Full Moon is the Sturgeon Moon of August 2015 after 4 days on 29 August 2015 at 18:35.
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% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1880" and ∠1898".
The Moon is 10 days young and navigating from the first to the middle 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°.
7 days since point of apogee on 18 August 2015 at 02:33 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 30 August 2015 at 15:24 in ♓ Pisces.
The Moon is 381 356 km (236 964 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 358 289 km (222 630 mi).
7 days after ascending node on 17 August 2015 at 23:05 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 31 August 2015 at 10:16 in ♈ Aries.
At 03:44 the Moon is meeting its standstill point to reach South declination of ∠-18.206°. Over the upcoming 12 days the lunar orbit is going to tilt northward to face maximum declination of ∠18.163° at the point of next northern standstill in ♊ Gemini on 6 September 2015 at 17:06.
7 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the beginning to the first part of the lunar cycle.
In 4 days on 29 August 2015 at 18:35 in ♒ Aquarius 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.
