On 26 June, 2009 I took these photos while at an Amateur Radio Field Day site in Goldendale, Washington State . As sunset progressed these clouds became more pronounced, then vanished very quickly as they lost their light. They were a pale yellowish-blue in color and were arranged roughly north-south in even standing-wave patterns. Dan Petersen, La Center, WA
