Waning Gibbous on . The illuminated surface of the moon is 91% and getting smaller. The lunar cycle is 17 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 about ∠10° of ♈ Aries tropical zodiac sector.
Previous main lunar phase is the Full Moon before 3 days on 26 August 2018 at 11:56.
Next Full Moon is the Harvest Moon of September 2018 after 26 days on 25 September 2018 at 02:53.
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 3.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1830" and ∠1900".
The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 230 of Meeus index or 1183 from Brown series.
The length of this lunation is 29 days, 8 hours and 4 minutes and it is 1 hour and 41 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 4 hours and 40 minutes shorter than the mean synodic month length. It is 1 hour and 29 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 ∠11.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠28°.
6 days since point of apogee on 23 August 2018 at 11:23 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 8 September 2018 at 01:21 in ♌ Leo.
The Moon is 391 577 km (243 315 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 361 355 km (224 536 mi).
5 days after descending node on 24 August 2018 at 04:51 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 6 September 2018 at 22:42 in ♋ Cancer.
7 days since the last southern standstill on 22 August 2018 at 02:58 in ♑ Capricorn when the Moon has reached South declination of ∠-20.773° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠20.837° at the point of next northern standstill on 5 September 2018 at 06:56 in ♋ Cancer.
18 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.
In 11 days on 9 September 2018 at 18:01 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.
