Waning Crescent on . The illuminated surface of the moon is 17% and getting smaller. The lunar cycle is 25 days old.
The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Main moon phases of the following lunar cycle.
Moon is passing about ∠22° of ♊ Gemini tropical zodiac sector.
Previous main lunar phase is the Last Quarter before 3 days on 29 July 2013 at 17:43.
Next Full Moon is the Sturgeon Moon of August 2013 after 18 days on 21 August 2013 at 01:45.
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 ∠1770" and ∠1891".
The Moon is 25 days old and navigating from the second to the final part of the current synodic month. This is lunation 167 of Meeus index or 1120 from Brown series.
The length of this lunation is 29 days, 14 hours and 36 minutes and it is 51 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 52 minutes longer than the mean synodic month length. It is 5 hours and 11 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 ∠191.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠216.9°.
11 days since point of perigee on 21 July 2013 at 20:27 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 3 August 2013 at 08:53 in ♋ Cancer.
The Moon is 404 866 km (251 572 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 405 834 km (252 174 mi).
3 days after descending node on 30 July 2013 at 05:50 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 13 August 2013 at 16:20 in ♏ Scorpio.
At 09:24 the Moon is meeting its standstill point to reach North declination of ∠20.025°. Over the upcoming 14 days the lunar orbit is going to tilt southward to face maximum declination of ∠-19.906° at the point of next southern standstill in ♐ Sagittarius on 16 August 2013 at 12:06.
15 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.
In 4 days on 6 August 2013 at 21:51 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.
