A HALO around the sun taken by Brittany Chandler in Okinawa, Japan and forwarded to us by Kris Brummel. This is caused as sunlight is "refracted" or "bent" as it travels through high clouds composed of ice crystals.

One of a number of beautiful shots of Saturday's prism-like array of colors on the high clouds which were in the area-a phenomenon known as a CIRCUMHORIZONTAL ARC.  This shot was taken at Hassert Park within the Lockport Township Park District by Morgan Marie Williams.

Beautiful Sunday sky—a mix of high and mid-level clouds—even a jet contrail.

A sure sign of approasching warm weathre is the return of the brilliantly-colored circumhorizontal arc to Chicago area skies.  This  atmospheric phenomenon sometimes called a fire rainbow is caused by the refraction of light through the ice crystals in cirrus clouds. It only occurs when the sun is high in the sky, 58º or higher above the horizon, so at Chicago's latitude it can only be seen from about mid April to late August.
The American Meteorological Society's Glossary of Meteorology explains that the most colorful circumhorizontal arcs occur when the sun is at an elevation of about 68º above the horizon. The peak solar elevation Saturday afternoon was 64.3 degrees.  Thanks to  Mary Beth Turone of Romeoville and Rob Vaupel of Naperville for capturing these shots on Saturday afternoon.
