Waning Gibbous on . The illuminated surface of the moon is 80% 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 2 August 2012 at 03:27.
Next Full Moon is the Sturgeon Moon of August 2012 after 25 days on 31 August 2012 at 13:58.
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 4.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1802" and ∠1892".
The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 155 of Meeus index or 1108 from Brown series.
The length of this lunation is 29 days, 11 hours and 30 minutes and it is 1 hour and 14 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 1 hour and 14 minutes shorter than the mean synodic month length. It is 4 hours and 55 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 ∠248.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠283.7°.
8 days since point of perigee on 29 July 2012 at 08:30 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next apogee on 10 August 2012 at 10:51 in ♉ Taurus.
The Moon is 397 770 km (247 163 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 404 125 km (251 112 mi).
9 days after ascending node on 28 July 2012 at 10:34 in ♐ Sagittarius 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 11 August 2012 at 00:04 in ♊ Gemini.
7 days since the last southern standstill on 29 July 2012 at 12:11 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.592° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠21.492° at the point of next northern standstill on 12 August 2012 at 09:47 in ♊ Gemini.
9 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the beginning to the first part of the lunar cycle.
In 11 days on 17 August 2012 at 15:54 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.
