Previous main lunar phase is the First Quarter before 5 days on 15 December 2018 at 11:49.
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.
Lunar disc appears visually 2.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1895" and ∠1950".
Next Full Moon is the Cold Moon of December 2018 after 2 days on 22 December 2018 at 17:49.
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 12 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 234 of Meeus index or 1187 from Brown series.
Length of current 234 lunation is 29 days, 18 hours and 8 minutes. It is 1 hour and 27 minutes shorter than next lunation 235 length.
Length of current synodic month is 5 hours and 24 minutes longer than the mean length of synodic month, but it is still 1 hour and 39 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠116.6°. At beginning of next synodic month true anomaly will be ∠149.4°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
7 days after point of apogee on 12 December 2018 at 12:25 in ♒ Aquarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 3 days, until it get to the point of next perigee on 24 December 2018 at 09:52 in ♋ Cancer.
Moon is 378 244 km (235 030 mi) away from Earth on this date. Moon moves closer next 3 days until perigee, when Earth-Moon distance will reach 361 060 km (224 352 mi).
9 days after its descending node on 10 December 2018 at 17:57 in ♑ Capricorn, the Moon is following the southern part of its orbit for the next 3 days, until it will cross the ecliptic from South to North in ascending node on 24 December 2018 at 11:54 in ♋ Cancer.
23 days after beginning of current draconic month in ♋ Cancer, the Moon is moving from the second to the final part of it.
11 days after previous South standstill on 9 December 2018 at 11:12 in ♑ Capricorn, when Moon has reached southern declination of ∠-21.539°. Next 2 days the lunar orbit moves northward to face North declination of ∠21.550° in the next northern standstill on 23 December 2018 at 11:48 in ♋ Cancer.
After 2 days on 22 December 2018 at 17:49 in ♊ Gemini, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
