Waning Crescent on . The illuminated surface of the moon is 15% 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 first ∠2° of ♐ Sagittarius tropical zodiac sector.
Previous main lunar phase is the Last Quarter before 3 days on 5 January 2013 at 03:58.
Next Full Moon is the Wolf Moon of January 2013 after 18 days on 27 January 2013 at 04:38.
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 1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1951".
The Moon is 25 days old and navigating from the second to the final part of the current synodic month. This is lunation 160 of Meeus index or 1113 from Brown series.
The length of this lunation is 29 days, 11 hours and 2 minutes and it is 34 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 1 hour and 42 minutes shorter than the mean synodic month length. It is 4 hours and 27 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 ∠6.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠23.3°.
13 days since point of apogee on 25 December 2012 at 21:19 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 10 January 2013 at 10:26 in ♑ Capricorn.
The Moon is 363 599 km (225 930 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 360 048 km (223 723 mi).
1 day after ascending node on 7 January 2013 at 23:50 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 21 January 2013 at 01:19 in ♉ Taurus.
12 days since the last northern standstill on 26 December 2012 at 21:24 in ♊ Gemini when the Moon has reached North declination of ∠20.927° the lunar orbit is extending southward over the next day to face maximum declination of ∠-20.879° at the point of next southern standstill on 9 January 2013 at 15:22 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 3 days on 11 January 2013 at 19:44 in ♑ Capricorn 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.
