Waxing Gibbous on . The illuminated surface of the moon is 75% and growing larger. The lunar cycle is 10 days young.
The moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Main moon phases of the following lunar cycle.
Moon is leaving the last ∠4° of ♏ Scorpio tropical zodiac sector and will enter ♐ Sagittarius later.
Previous main lunar phase is the First Quarter before 2 days on 16 July 2013 at 03:18.
Next Full Moon is the Buck Moon of July 2013 after 4 days on 22 July 2013 at 18:15.
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 3.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1952" and ∠1888".
The Moon is 10 days young and navigating from the first to the middle 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 apogee on 7 July 2013 at 00:36 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 21 July 2013 at 20:27 in ♑ Capricorn.
The Moon is 367 166 km (228 146 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 358 402 km (222 701 mi).
1 day after ascending node on 17 July 2013 at 14:58 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 30 July 2013 at 05:50 in ♉ Taurus.
12 days since the last northern standstill on 6 July 2013 at 02:09 in ♊ Gemini when the Moon has reached North declination of ∠20.170° the lunar orbit is extending southward over the next day to face maximum declination of ∠-20.097° at the point of next southern standstill on 20 July 2013 at 03:12 in ♐ Sagittarius.
1 day since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first part of the lunar cycle.
In 4 days on 22 July 2013 at 18:15 in ♑ Capricorn the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
