Waning Gibbous on . The illuminated surface of the moon is 86% and getting smaller. The lunar cycle is 18 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 leaving the last ∠3° of ♋ Cancer tropical zodiac sector and will enter ♌ Leo later.
Previous main lunar phase is the Full Moon before 3 days on 2 December 2009 at 07:30.
Next Full Moon is the Cold Moon of December 2009 after 26 days on 31 December 2009 at 19:13.
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 1.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1947".
The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 122 of Meeus index or 1075 from Brown series.
The length of this lunation is 29 days, 16 hours and 48 minutes and it is 2 hours and 21 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 4 hours and 4 minutes longer than the mean synodic month length. It is 2 hours and 59 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 ∠99.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠135.6°.
1 day since point of perigee on 4 December 2009 at 14:12 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 15 days until the Moon reaches the point of next apogee on 20 December 2009 at 14:54 in ♒ Aquarius.
The Moon is 363 640 km (225 955 mi) away from Earth and getting further over the next 15 days until the point apogee when Earth-Moon distance is going to be 405 731 km (252 110 mi).
Moon is in descending node in ♋ Cancer at 03:18 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 13 days until Moon's next ascending node later on 18 December 2009 at 16:41 in ♑ Capricorn.
2 days since the last northern standstill on 2 December 2009 at 23:37 in ♊ Gemini when the Moon has reached North declination of ∠25.772° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-25.769° at the point of next southern standstill on 16 December 2009 at 02:38 in ♐ Sagittarius.
14 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the second to the final part of the lunar cycle.
In 11 days on 16 December 2009 at 12:02 in ♐ Sagittarius 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.
