Pileus, Shadows, and Colors 8/17 2010
My dad and I were by the river and were treated with a beautiful sky August 17 last year. There were large cumulus congestus clouds everywhere topped with pileus clouds. Pileus clouds tend to form all at once, meaning the droplets are of uniform size. That means good iridescence! And just that happened, I've not yet seen iridescence as good as this day. After that, long shadows were cast on the upper cloud layer.
