Waning Crescent is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 22% and getting smaller.
Previous main lunar phase is the Last Quarter before 3 days on 28 August 2013 at 09:35.
Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.
Lunar disc appears visually 7.27% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1901".
Next Full Moon is the Harvest Moon of September after 18 days on 19 September 2013 at 11:13.
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 24 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 168 of Meeus index or 1121 from Brown series.
Length of current 168 lunation is 29 days, 13 hours and 45 minutes. It is 47 minutes longer than next lunation 169.
Length of current synodic month is 1 hour and 1 minute longer than the mean length of synodic month, but it is still 6 hours and 2 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠216.9°. At the beginning of next synodic month true anomaly is ∠249.2°. 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°).
1 day after point of apogee on 30 August 2013 at 23:46, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 15 days until it gets to the point of perigee on 15 September 2013 at 16:34.
Moon is 405 460 km (251 941 mi) away from Earth on this date. At previous apogee point before 1 day, distance is 404 883 km (251 583 mi). Moon moves closer next 15 days until perigee, when Earth-Moon distance reaches 367 388 km (228 284 mi).
5 days after its descending node on 26 August 2013 at 08:19, 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 9 September 2013 at 17:29.
17 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 29 August 2013 at 17:03, when Moon reaches northern declination of ∠19.801°, lunar orbit moves southward for the next 12 days to face South declination of ∠-19.685° in the next southern standstill on 12 September 2013 at 18:30.
After 4 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 5 September 2013 at 11:36.
