Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Lunar disc appears visually 9.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1774" and ∠1950".
Next Full Moon is the Cold Moon of December 2009 after 13 days on 31 December 2009 at 19:13.
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.
The Moon is 2 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 123 of Meeus index or 1076 from Brown series.
Length of current 123 lunation is 29 days, 19 hours and 9 minutes. This is the year's longest synodic month of 2009. It is 31 minutes shorter than next lunation 124 length.
Length of current synodic month is 6 hours and 25 minutes longer than the mean length of synodic month, but it is still 38 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠135.6°. At beginning of next synodic month true anomaly will be ∠164.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
13 days after point of perigee on 4 December 2009 at 14:12 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 2 days, until it get to the point of next apogee on 20 December 2009 at 14:54 in ♒ Aquarius.
Moon is 404 074 km (251 080 mi) away from Earth on this date. Moon moves farther next 2 days until apogee, when Earth-Moon distance will reach 405 731 km (252 110 mi).
Moon is in ascending node in ♑ Capricorn at 16:41 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 14 days to meet descending node on 1 January 2010 at 12:30 in ♋ Cancer.
At 16:41 on this date the Moon is completing its previous draconic month and is entering the new one.
2 days after previous South standstill on 16 December 2009 at 02:38 in ♐ Sagittarius, when Moon has reached southern declination of ∠-25.769°. Next 11 days the lunar orbit moves northward to face North declination of ∠25.787° in the next northern standstill on 30 December 2009 at 10:09 in ♊ Gemini.
After 13 days on 31 December 2009 at 19:13 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
