Last Quarter on . The illuminated surface of the moon is 58% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 30 June 2013 at 04:54 UTC.
The moon rises at midnight and sets at noon. It is visible to the south in the morning.

Main moon phases of the following lunar cycle.
Moon is leaving the last ∠1° of ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.
Next Full Moon is the Buck Moon of July 2013 after 23 days on 22 July 2013 at 18:15.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunar disc appears visually 0.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1876" and ∠1887".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 166 of Meeus index or 1119 from Brown series.
The length of this lunation is 29 days, 15 hours and 18 minutes and it is 42 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 34 minutes longer than the mean synodic month length. It is 4 hours and 29 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 ∠168.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠191.6°.
6 days since point of perigee on 23 June 2013 at 11:09 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 7 days until the Moon reaches the point of next apogee on 7 July 2013 at 00:36 in ♋ Cancer.
The Moon is 381 991 km (237 358 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 493 km (252 583 mi).
9 days after ascending node on 20 June 2013 at 09:51 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from North to South in descending node on 3 July 2013 at 04:15 in ♉ Taurus.
6 days since the last southern standstill on 22 June 2013 at 16:11 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.186° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠20.170° at the point of next northern standstill on 6 July 2013 at 02:09 in ♊ Gemini.
9 days 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 8 days on 8 July 2013 at 07:14 in ♋ Cancer 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.
