Waning Gibbous on . The illuminated surface of the moon is 82% and getting smaller. The lunar cycle is 19 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 ∠8° of ♈ Aries tropical zodiac sector.
Previous main lunar phase is the Full Moon before 4 days on 6 August 2009 at 00:55.
Next Full Moon is the Harvest Moon of September 2009 after 25 days on 4 September 2009 at 16:03.
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 2.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1841" and ∠1893".
The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 118 of Meeus index or 1071 from Brown series.
The length of this lunation is 29 days, 7 hours and 27 minutes and it is 1 hour and 16 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 5 hours and 17 minutes shorter than the mean synodic month length. It is 52 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 ∠4.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠20.3°.
6 days since point of apogee on 4 August 2009 at 00:42 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 19 August 2009 at 04:53 in ♌ Leo.
The Moon is 389 321 km (241 913 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 359 642 km (223 471 mi).
5 days after ascending node on 4 August 2009 at 21:42 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 18 August 2009 at 14:06 in ♋ Cancer.
8 days since the last southern standstill on 1 August 2009 at 13:28 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.478° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠26.442° at the point of next northern standstill on 15 August 2009 at 21:54 in ♊ Gemini.
5 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.
In 9 days on 20 August 2009 at 10:01 in ♌ Leo 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.
