The Moon was dipped in the deep coppery hues caused by atmospheric refraction. When the Moon enters the Earth’s shadow completely, the refracted sunlight is still able to reach the Moon and light it a little. This light passes through the deep layers of the Earth’s atmosphere, which filters the blue end of the spectrum more, and so the remaining light is deep brown, red, orange or yellow. "They" say it's one of the signs in Revelation, but we seem to be nearly submersed in "signs" from Revelation. Hmmm.
Something interesting to note about this particular Winter Solstice and all the extra high vibrational activating energy available to us is this. When you add up the numbers of the month day and year, 12-21-2010 is actually a 9 in sacred numerology. (12=3, 21=3, 2010=3/3+3+3=9) 9 came into the universe as energizing endings and beginnings, exhales and inhales.
