Previous main lunar phase is the New Moon before 3 days on 16 December 2009 at 12:02.
Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.
Moon is passing about ∠12° of ♒ Aquarius tropical zodiac sector.
Lunar disc appears visually 9.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1950".
Next Full Moon is the Cold Moon of December 2009 after 11 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.
The Moon is 4 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°).
Moon is reaching point of apogee on this date at 14:54, this is 16 days after last perigee on 4 December 2009 at 14:12 in ♋ Cancer. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 12 days ahead, until it will get to the point of next perigee on 1 January 2010 at 20:36 in ♋ Cancer.
This apogee Moon is 405 731 km (252 110 mi) away from Earth. It is 323 km farther than the mean apogee distance, but it is still 978 km closer than the farthest apogee of 21st century.
1 day after its ascending node on 18 December 2009 at 16:41 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 12 days, until it will cross the ecliptic from North to South in descending node on 1 January 2010 at 12:30 in ♋ Cancer.
1 day after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the beginning to the first part of it.
4 days after previous South standstill on 16 December 2009 at 02:38 in ♐ Sagittarius, when Moon has reached southern declination of ∠-25.769°. Next 9 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 11 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.
