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.
Previous main lunar phase is the Full Moon before 6 days on 17 December 2013 at 09:28.
Next Full Moon is the Wolf Moon of January after 23 days on 16 January 2014 at 04:52.
Moon is passing about ∠8° of Virgo tropical zodiac sector.
Lunar disc appears visually 8.12% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1799" and ∠1951".
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 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 172 of Meeus index or 1125 from Brown series.
Length of current 172 lunation is 29 days, 10 hours and 52 minutes. It is 28 minutes longer than next lunation 173. This is the shortest synodic month of 2013.
Length of current synodic month is 1 hour and 52 minutes shorter than the mean length of synodic month, but it is still 4 hours and 17 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠336.4°. At the beginning of next synodic month true anomaly is ∠353°. 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°).
3 days after point of apogee on 19 December 2013 at 23:49, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 9 days until it gets to the point of perigee on 1 January 2014 at 21:00.
Moon is 398 518 km (247 628 mi) away from Earth on this date. At previous apogee point before 3 days, distance is 406 269 km (252 444 mi). Moon moves closer next 9 days until perigee, when Earth-Moon distance reaches 356 922 km (221 781 mi).
10 days after its descending node on 13 December 2013 at 10:10, the Moon follows the southern part of its orbit for the next 4 days untill it crosses the ecliptic from South to North in ascending node on 28 December 2013 at 00:21.
22 days after its beginning, the Moon is moving from the second to the final part of current draconic month.
6 days after previous North standstill on 17 December 2013 at 01:00, when Moon reaches northern declination of ∠19.570°, lunar orbit moves southward for the next 7 days to face South declination of ∠-19.537° in the next southern standstill on 31 December 2013 at 04:49.
After 8 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 1 January 2014 at 11:14.
