THE EFFECT OF OZONE ON THE LUNAR ECLIPSE:

When you think of a lunar eclipse, the color that comes to mind is red. The core of Earth's shadow is reddened by atmospheric scattering, and when that shadow falls across the Moon, the lunar landscape turns as red as a sunset. Yet some observers of the Jan. 31st lunar eclipse saw another hue--turquoise-blue: George Ionas sends this picture from Palmerston North, New Zealand:

"A few seconds after totality ended, a soft blue band appeared," says Ionas. "Could this be the color of Earth's atmosphere projected onto the lunar surface?"

That's not far off. The source of the turquoise is ozone. Eclipse researcher Richard Keen, an Emeritus professor at 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 turquoise-blue fringe around the red.

Keen was in Hawaii for the eclipse, and he saw it, too. "The blue band was easy to see through binoculars during the last minutes of totality, although naked-eye observers might have missed it. A number of pictures submitted to Spaceweather.com do justice to the visual appearance."
