Previous main lunar phase is the Full Moon before 2 days on 21 December 2010 at 08:13.
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.
Lunar disc appears visually 0.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1935" and ∠1951".
Next Full Moon is the Wolf Moon of January 2011 after 27 days on 19 January 2011 at 21:21.
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 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 135 of Meeus index or 1088 from Brown series.
Length of current 135 lunation is 29 days, 15 hours and 27 minutes. It is 2 hours and 1 minute shorter than next lunation 136 length.
Length of current synodic month is 2 hours and 43 minutes longer than the mean length of synodic month, but it is still 4 hours and 20 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠67°. At beginning of next synodic month true anomaly will be ∠103.5°. 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°).
10 days after point of apogee on 13 December 2010 at 08:34 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 2 days, until it get to the point of next perigee on 25 December 2010 at 12:24 in ♌ Leo.
Moon is 370 369 km (230 137 mi) away from Earth on this date. Moon moves closer next 2 days until perigee, when Earth-Moon distance will reach 368 463 km (228 952 mi).
1 day after its descending node on 21 December 2010 at 14:08 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 11 days, until it will cross the ecliptic from South to North in ascending node on 3 January 2011 at 12:48 in ♑ Capricorn.
16 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the second to the final part of it.
2 days after previous North standstill on 20 December 2010 at 12:37 in ♊ Gemini, when Moon has reached northern declination of ∠24.238°. Next 9 days the lunar orbit moves southward to face South declination of ∠-24.242° in the next southern standstill on 2 January 2011 at 10:06 in ♐ Sagittarius.
After 11 days on 4 January 2011 at 09:03 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
