Waning Gibbous is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 88% and getting smaller.
Previous main lunar phase is the Full Moon before 3 days on 18 October 2013 at 23:38.
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 7.66% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1786" and ∠1928".
Next Full Moon is the Beaver Moon of November after 26 days on 17 November 2013 at 15:16.
Moon is passing about ∠10° of Gemini 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 170 of Meeus index or 1123 from Brown series.
Length of current 170 lunation is 29 days, 12 hours and 15 minutes. It is 43 minutes longer than next lunation 171.
Length of current synodic month is 29 minutes shorter than the mean length of synodic month, but it is still 5 hours and 40 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠285.3°. At the beginning of next synodic month true anomaly is ∠315°. 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°).
11 days after point of perigee on 10 October 2013 at 23:06, lunar orbit gets wider while the Moon moves outward the Earth. It keeps this direction for next 3 days until it gets to the point of apogee on 25 October 2013 at 14:25.
Moon is 401 295 km (249 353 mi) away from Earth on this date. At previous perigee point before 11 days, distance is 369 813 km (229 791 mi). Moon moves farther next 3 days until apogee, when Earth-Moon distance reaches 404 561 km (251 383 mi).
2 days after its descending node on 19 October 2013 at 21:47, the Moon follows the southern part of its orbit for the next 11 days untill it crosses the ecliptic from South to North in ascending node on 3 November 2013 at 06:52.
15 days after its beginning, the Moon is moving from the second to the final part of current draconic month.
12 days after previous South standstill on 9 October 2013 at 23:52, when Moon reaches southern declination of ∠-19.537°, lunar orbit moves northward for the next 1 day to face North declination of ∠19.509° in the next northern standstill on 23 October 2013 at 09:13.
After 12 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 3 November 2013 at 12:50.
