Previous main lunar phase is the First Quarter before 2 days on 18 December 2015 at 15:14.
Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.
Moon is passing about ∠7° of ♉ Taurus tropical zodiac sector.
Lunar disc appears visually 0.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1964" and ∠1951".
Next Full Moon is the Cold Moon of December 2015 after 3 days on 25 December 2015 at 11:11.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
The Moon is 10 days young. Earth's natural satellite is moving from the first to the middle 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°).
Moon is reaching point of perigee on this date at 08:53, this is 15 days after last apogee on 5 December 2015 at 14:56 in ♎ Libra. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 11 days ahead, until it will get to the point of next apogee on 2 January 2016 at 11:53 in ♎ Libra.
This perigee Moon is 368 418 km (228 924 mi) away from Earth. It is 5 910 km closer than the mean perigee distance, but it is still 1 938 km farther than the closest perigee of 21st century.
2 days after its descending node on 18 December 2015 at 15:13 in ♓ Pisces, the Moon is following the southern part of its orbit for the next 10 days, until it will cross the ecliptic from South to North in ascending node on 31 December 2015 at 20:19 in ♍ Virgo.
16 days after beginning of current draconic month in ♍ Virgo, the Moon is moving from the second to the final part of it.
9 days after previous South standstill on 12 December 2015 at 08:15 in ♑ Capricorn, when Moon has reached southern declination of ∠-18.438°. Next 3 days the lunar orbit moves northward to face North declination of ∠18.444° in the next northern standstill on 25 December 2015 at 07:30 in ♋ Cancer.
After 3 days on 25 December 2015 at 11:11 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
