Previous main lunar phase is the Full Moon before 2 days on 2 December 2009 at 07:30.
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.
Moon is passing about ∠12° of ♋ Cancer tropical zodiac sector.
Lunar disc appears visually 0.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1963" and ∠1947".
Next Full Moon is the Cold Moon of December 2009 after 27 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 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 122 of Meeus index or 1075 from Brown series.
Length of current 122 lunation is 29 days, 16 hours and 48 minutes. It is 2 hours and 21 minutes shorter than next lunation 123 length.
Length of current synodic month is 4 hours and 4 minutes longer than the mean length of synodic month, but it is still 2 hours and 59 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠99.9°. At beginning of next synodic month true anomaly will be ∠135.6°. 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 perigee on this date at 14:12, this is 11 days after last apogee on 22 November 2009 at 20:07 in ♒ Aquarius. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 16 days ahead, until it will get to the point of next apogee on 20 December 2009 at 14:54 in ♒ Aquarius.
This perigee Moon is 363 479 km (225 855 mi) away from Earth. It is 971 km closer than the mean perigee distance, but it is still 6 877 km farther than the closest perigee of 21st century.
13 days after its ascending node on 21 November 2009 at 11:34 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 5 December 2009 at 03:18 in ♋ Cancer.
13 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the beginning to the first part of it.
1 day after previous North standstill on 2 December 2009 at 23:37 in ♊ Gemini, when Moon has reached northern declination of ∠25.772°. Next 11 days the lunar orbit moves southward to face South declination of ∠-25.769° in the next southern standstill on 16 December 2009 at 02:38 in ♐ Sagittarius.
After 12 days on 16 December 2009 at 12:02 in ♐ Sagittarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
