Orion's Umbra

Google+ ~ Zazzle ~ Blog


17 minutes into Umbra, she was still glowing blue on the edge. And what a great site she was! Of course I had to blind pan it as it was nowhere near Orion. Some noise redux and a crop, otherwise no PS.


About the blueish glow: The color temperature setting on camera was set in the cool range to draw this out. Eclipse researcher Dr. Richard Keen of the University of Colorado explains:


"Most of the light illuminating the Moon passes through the stratosphere, and 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 can be seen, he says, as a blue fringe around the red core of Earth's shadow.
