Waning Gibbous is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 92% and getting smaller.
Previous main lunar phase is the Full Moon before 2 days on 10 December 2011 at 14:36.
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.
Lunar disc appears visually 4.63% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1861" and ∠1949".
Next Full Moon is the Wolf Moon of January after 26 days on 9 January 2012 at 07:30.
Moon is passing about ∠24° of Cancer tropical zodiac sector.
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.
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 147 of Meeus index or 1100 from Brown series.
Length of current 147 lunation is 29 days, 11 hours and 57 minutes. It is 1 hour and 36 minutes shorter than next lunation 148.
Length of current synodic month is 47 minutes shorter than the mean length of synodic month, but it is still 5 hours and 22 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠21.6°. At the beginning of next synodic month true anomaly is ∠42.1°. The length of upcoming synodic months increases since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
7 days after point of apogee on 6 December 2011 at 01:13, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 8 days until it gets to the point of perigee on 22 December 2011 at 02:56.
Moon is 385 168 km (239 332 mi) away from Earth on this date. At previous apogee point before 7 days, distance is 405 414 km (251 913 mi). Moon moves closer next 8 days until perigee, when Earth-Moon distance reaches 364 801 km (226 677 mi).
3 days after its descending node on 10 December 2011 at 07:04, the Moon follows the southern part of its orbit for the next 9 days untill it crosses the ecliptic from South to North in ascending node on 23 December 2011 at 11:36.
17 days after its beginning, the Moon is moving from the second to the final part of current draconic month.
2 days after previous North standstill on 10 December 2011 at 13:37, when Moon reaches northern declination of ∠22.554°, lunar orbit moves southward for the next 10 days to face South declination of ∠-22.554° in the next southern standstill on 23 December 2011 at 17:25.
After 11 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 24 December 2011 at 18:06.
