Lunar disc appears visually 3.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1891" and ∠1951".
The Full Moon this days is the Cold of December 2010.
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.

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°).
8 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 4 days, until it get to the point of next perigee on 25 December 2010 at 12:24 in ♌ Leo.

1 day after previous North standstill on 20 December 2010 at 12:37 in ♊ Gemini, when Moon has reached northern declination of ∠24.238°. Next 11 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.
The Moon is in Full Moon geocentric opposition with the Sun on this date and this alignment forms Sun-Earth-Moon syzygy.
