Waning Gibbous on . The illuminated surface of the moon is 66% and getting smaller. The lunar cycle is 20 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 6 days on 15 July 2011 at 06:40.
Next Full Moon is the Sturgeon Moon of August 2011 after 23 days on 13 August 2011 at 18:58.
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 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1888".
The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 142 of Meeus index or 1095 from Brown series.
The length of this lunation is 29 days, 9 hours and 46 minutes and it is 1 hour and 22 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 2 hours and 58 minutes shorter than the mean synodic month length. It is 3 hours and 11 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 ∠283.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠312.1°.
Moon is at apogee at 22:46 about 14 days since last perigee on 7 July 2011 at 14:04 in ♍ Virgo the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 2 August 2011 at 20:59 in ♍ Virgo.
This apogee Moon is 404 358 km (251 256 mi) away from Earth. It is 1 050 km further than the mean apogee distance, but it is still 2 351 km closer than the farthest apogee of 21st century.
8 days after ascending node on 13 July 2011 at 02:27 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from North to South in descending node on 27 July 2011 at 12:03 in ♊ Gemini.
8 days since the last southern standstill on 12 July 2011 at 16:51 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.383° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠23.333° at the point of next northern standstill on 27 July 2011 at 03:02 in ♊ Gemini.
8 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 9 days on 30 July 2011 at 18:40 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.
