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.

This fire rainbow, or more properly, a circumhorizontal arc, appeared and several coastal residents got a photo of it. Donna Woodbury photographed it from Anchor Bay Beach. In Donna's second photo the fire rainbow is at the bottom and a portion of the halo around the sun appears. A halo can often predict rain.

Peggy Berryhill only had her phone camera but she captured it too. She said the colors were much more vibrant that what her photo shows.

And lastly Christina Chapman got this photo, which also shows the halo around the sun.

A circumhorizontal arc occurs when the sun is refracted through ice crystals.
