2011/12/10 Total Lunar Eclipse

I drove up to Henry Coe state park for its excellent western horizon despite of the poor weather forecast. The mid and high clouds rolled in and covered most of the sky before midnight. At 3:30AM, about an hour before the first contact, the high clouds finally broke up. I setup my telescopes quickly – AT111EDT for imaging and AT72 for visual. Weather remained favorable throughout the eclipse, scattered high clouds came and went, only blocked the moon from time to time.

In this 5s exposure, in addition to the usual red/orange color of the lunar eclipse, if you look closer you will also notice pinkish and blueish color (turquoise) near the shadow of the Earth.

The eclipse coincided with Geminids which peaked on 12~13th. Since the moon conveniently located near the radiant, my kid and I were awarded with about a dozen of meteors.

The sky started to brighten at 2nd contact. The moon became fainter and fainter, as the sky brightened and the moon set in the clouds/haze .At the greatest eclipse the moon became so faint that it was difficult to spot. At 6:40AM, last sight of the moon disappeared over the silicon valley.
