Spokane WA Circumhorizon Arc IV
Image index The Spokane display of June 3, 2006 will probably rank as one of the brightest and most widely observed circumhorizon arcs. Sue Wild-Kirn took this during a Cystic Fibrosis walk at Gonzaga University & Centennial Park. " The arc literally brought the walk to a halt for quite some time!"
