Waning Gibbous on . The illuminated surface of the moon is 73% 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 first ∠4° of ♋ Cancer tropical zodiac sector.
Previous main lunar phase is the Full Moon before 5 days on 18 October 2013 at 23:38.
Next Full Moon is the Beaver Moon of November 2013 after 24 days on 17 November 2013 at 15:16.
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 8.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1930".
The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 170 of Meeus index or 1123 from Brown series.
The length of this lunation is 29 days, 12 hours and 15 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 29 minutes shorter than the mean synodic month length. It is 5 hours and 40 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 ∠285.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠315°.
13 days since point of perigee on 10 October 2013 at 23:06 in ♐ Sagittarius 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 25 October 2013 at 14:25 in ♋ Cancer.
The Moon is 405 060 km (251 693 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 561 km (251 383 mi).
4 days after descending node on 19 October 2013 at 21:47 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 November 2013 at 06:52 in ♏ Scorpio.
1 day since the last northern standstill on 23 October 2013 at 09:13 in ♊ Gemini when the Moon has reached North declination of ∠19.509° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-19.511° at the point of next southern standstill on 6 November 2013 at 06:43 in ♐ Sagittarius.
17 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 10 days on 3 November 2013 at 12:50 in ♏ Scorpio 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.
