Waning Gibbous is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 90% and getting smaller.
Previous main lunar phase is the Full Moon before 3 days on 30 September 2012 at 03:19.
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 7.99% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1918".
Next Full Moon is the Hunter Moon of October after 26 days on 29 October 2012 at 19:50.
Moon is passing about ∠18° of Taurus 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 157 of Meeus index or 1110 from Brown series.
Length of current 157 lunation is 29 days, 9 hours and 52 minutes. It is 13 minutes shorter than next lunation 158. This is the shortest synodic month of 2012.
Length of current synodic month is 2 hours and 52 minutes shorter than the mean length of synodic month, but it is still 3 hours and 17 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠312.9°. At the beginning of next synodic month true anomaly is ∠334.3°. 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°).
14 days after point of perigee on 19 September 2012 at 02:52, 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 5 October 2012 at 00:43.
Moon is 404 783 km (251 521 mi) away from Earth on this date. At previous perigee point before 14 days, distance is 365 749 km (227 266 mi). Moon moves farther next 1 day until apogee, when Earth-Moon distance reaches 405 162 km (251 756 mi).
12 days after its ascending node on 20 September 2012 at 12:54, the Moon follows the northern part of its orbit for the next 1 day untill it crosses the ecliptic from North to South in descending node on 4 October 2012 at 05:15.
12 days after its beginning, the Moon is moving from the beginning to the first part of current draconic month.
11 days after previous South standstill on 22 September 2012 at 00:11, when Moon reaches southern declination of ∠-21.135°, lunar orbit moves northward for the next 2 days to face North declination of ∠21.024° in the next northern standstill on 6 October 2012 at 01:40.
After 12 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 15 October 2012 at 12:02.
