Waning Gibbous on . The illuminated surface of the moon is 95% and getting smaller. The lunar cycle is 17 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 ∠24° of ♈ Aries tropical zodiac sector.
Previous main lunar phase is the Full Moon before 2 days on 19 September 2013 at 11:13.
Next Full Moon is the Hunter Moon of October 2013 after 27 days on 18 October 2013 at 23:38.
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 3.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1848" and ∠1912".
The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 169 of Meeus index or 1122 from Brown series.
The length of this lunation is 29 days, 12 hours and 58 minutes and it is 43 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 14 minutes longer than the mean synodic month length. It is 6 hours and 49 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 ∠249.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠285.3°.
5 days since point of perigee on 15 September 2013 at 16:34 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 6 days until the Moon reaches the point of next apogee on 27 September 2013 at 18:17 in ♋ Cancer.
The Moon is 387 824 km (240 983 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 404 309 km (251 226 mi).
11 days after ascending node on 9 September 2013 at 17:29 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 22 September 2013 at 13:48 in ♉ Taurus.
8 days since the last southern standstill on 12 September 2013 at 18:30 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.685° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠19.599° at the point of next northern standstill on 26 September 2013 at 01:03 in ♊ Gemini.
11 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 13 days on 5 October 2013 at 00:35 in ♎ Libra 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.
