Recently Cathleen Crosby captured a photo of a Sun Dog, which is also called a Parhelion. This Sun Dog was seen out over the Pacific Ocean. It looks like several Ravens were flying by.
A Sun Dog is a rainbow in the sky but there are no rain clouds. It is formed when light rays pass through high cirrus clouds. The ice crystals in the clouds act as prisms and, if conditions are right, you get this rare phenomenon. Thanks to Cathleen for allowing me to share it with you here!
To see another rare cloud with a rainbow phenomenon, click here to see a cloud falling out of a cloud. It's amazing!http://www.mendonomasightings.com/2011/05/13/rare-cloud-phenomenon-a-cloud-falling-out-of-a-cloud/
