Waning Gibbous is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 87% and getting smaller.
Previous main lunar phase is the Full Moon before 3 days on 17 November 2013 at 15:16.
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 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1943".
Next Full Moon is the Cold Moon of December after 25 days on 17 December 2013 at 09:28.
Moon is passing about ∠12° 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 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 171 of Meeus index or 1124 from Brown series.
Length of current 171 lunation is 29 days, 11 hours and 32 minutes. It is 40 minutes longer than next lunation 172.
Length of current synodic month is 1 hour and 12 minutes shorter than the mean length of synodic month, but it is still 4 hours and 57 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠315°. At the beginning of next synodic month true anomaly is ∠336.4°. The length of upcoming synodic months decreases since the true anomaly gets closer to the value of New Moon at point of perigee (∠0°or∠360°).
15 days after point of perigee on 6 November 2013 at 09:28, lunar orbit gets wider while the Moon moves outward the Earth. It keeps this direction for next 1 day until it gets to the point of apogee on 22 November 2013 at 09:50.
Moon is 405 356 km (251 876 mi) away from Earth on this date. At previous perigee point before 15 days, distance is 365 362 km (227 025 mi). Moon moves farther next 1 day until apogee, when Earth-Moon distance reaches 405 446 km (251 932 mi).
5 days after its descending node on 16 November 2013 at 05:30, 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 30 November 2013 at 16:59.
18 days after its beginning, the Moon is moving from the second to the final part of current draconic month.
1 day after previous North standstill on 19 November 2013 at 17:18, when Moon reaches northern declination of ∠19.534°, lunar orbit moves southward for the next 12 days to face South declination of ∠-19.552° in the next southern standstill on 3 December 2013 at 16:38.
After 11 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 3 December 2013 at 00:22.
