Last Saturday, young Oly Perket saw fire in the blue sky. She wrote, “This was taken when Mom [Madeline Perket] and I were driving to Sebastopol.”

Oly photographed a beautiful atmospheric phenomenon called a circumhorizontal arc. They are often called fire rainbows, except they aren’t actual rainbows.  They are ice halos created when sunlight passes through high-altitude cirrus clouds.

Thanks to Oly for allowing me to share her photo with you here.

Foggy morning, sunny afternoon with temps in the 60's. It's the last day of spring!

We had some beautiful clouds last week. They must have been cirrus or cirrostratus clouds as those are the types of clouds a Circumhorizontal Arc might appear. Marilyn Green photographed this rather rare phenomenon.

 

They are formed by the refraction of the sun in ice crystals suspended in the clouds, a beautiful sight, indeed.

Thanks to Marilyn for allowing me to share her photo with you here.

Another HOT day on the Mendonoma coast! Beach weather, for sure.

Eric Duff recently photographed the sky at Cooks Beach. He actually capture a  circumhorizontal arc, also sometimes called a fire rainbow, and a halo around the sun.

These are both formed because of ice crystals in the atmosphere. They refract and reflect the light. Very wonderful photo. Thanks to Eric for allowing me to share it with you here.

The fog pulled back and we are having a sunny, mild day on the coast. Much warmer weather for the holiday weekend.

Ken Fischer saw this fire rainbow several weeks ago. He said it only lasted about two minutes.

Here's a larger one, which was taken by last year by Connie King.

No rainbows today - there is nothing but oh-so-blue sky here on the coast. It already feels like the holiday has begun!

Jan Jewell spotted the Circumhorizontal Arc, also called a Fire Rainbow, a few weeks ago.

A Common Raven can be seen flying by on the right. This phenomenon is caused by the refraction of sunlight in ice crystals found certain clouds, in particular cirrus clouds.

Here is another example of a fire rainbow, this one taken by Peggy Berryhill.
