Undulatus upon which Kit included the following sentiment: Oh, striated sentinels of the upper air, You gather in ranks like a silent parade, You do not hurry — the earth will turn for you; You simply drift, and the world tilts its head to watch. This example of undulatus was spotted over Oahu, Hawaii, US.

Gorgeously heavenly! What else can one say? A great shot, Jan. I especially like the sun rays radiating upwards and the golden back lit clouds. A memorable picture!
