Fire rainbows are the rarest of all naturally occurring atmospheric phenomena. For a fire rainbow to occur, cirrus clouds must be feet in the air with the precise amount of ice crystals, and the sun must hit the clouds at 58 degrees. (a/k/a Sun Doggies)
We had a fantastic lightening storm last nite, Aug Booms, low rumbles, actual lightening bolts (not the typical sheet lightening). Haven't had a good one in SW Puget Sound for years. a really good picture of an amazing set of lightning strikes.
