Lunar Eclipse September 27, 2015 Castle Rock, CO

The first image below was taken at 7:17pm MDT as the Earth's shadow takes a "bite" out of the moon.  The second image was taken at 8:13pm MDT near totality

During a lunar eclipse, most of the light illuminating the moon passes through the stratosphere, where it is reddened by scattering.  However, light passing through the upper stratosphere penetrates the ozone layer, which absorbs red light and actually makes the passing light ray bluer.  This relatively rare coloring can be seen in the upper right limb of the moon on the second image below.
