What a show in the sky today due to the cirrus clouds made up of ice crystals.

Calls of a sun dog where there appears to be another sun near the sun. Rainbows being reported and also a hole in the clouds.

In brief, the hole in the cloud formation is caused by falling ice crystals, evaportation, and wind.

Here is what it looked like today from Raymond Perry:Click for larger picture.

David Martin took this shot of what appears to be a rainbow today also:Click for larger image.

This has happened before as well.
