Previous main lunar phase is the Full Moon before 6 days on 25 December 2015 at 11:11.
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.
Moon is passing about ∠21° of ♍ Virgo tropical zodiac sector.
Lunar disc appears visually 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1776" and ∠1951".
Next Full Moon is the Wolf Moon of January 2016 after 23 days on 24 January 2016 at 01:46.
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.
The 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 197 of Meeus index or 1150 from Brown series.
Length of current 197 lunation is 29 days, 15 hours and 1 minute. It is 1 hour and 53 minutes longer than next lunation 198 length.
Length of current synodic month is 2 hours and 17 minutes longer than the mean length of synodic month, but it is still 4 hours and 46 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠255.6°. At the beginning of next synodic month true anomaly will be ∠292.2°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
10 days after point of perigee on 21 December 2015 at 08:53 in ♉ Taurus. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 2 January 2016 at 11:53 in ♎ Libra.
Moon is 403 510 km (250 729 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 404 279 km (251 207 mi).
Moon is in ascending node in ♍ Virgo at 20:19 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 14 days to meet descending node on 14 January 2016 at 15:48 in ♓ Pisces.
At 20:19 on this date the Moon is completing its previous draconic month and is entering the new one.
6 days after previous North standstill on 25 December 2015 at 07:30 in ♋ Cancer, when Moon has reached northern declination of ∠18.444°. Next 8 days the lunar orbit moves southward to face South declination of ∠-18.420° in the next southern standstill on 8 January 2016 at 17:56 in ♐ Sagittarius.
After 9 days on 10 January 2016 at 01:30 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
