Picture of Blue Sun

Ever seen a 'Blue Sun'? Take a look at the picture above. This blue sun picture was captured from the PyramidCam, that transmits live image of the pyramids every 30 seconds. This particular image was saved by Tom Hartlove on December 14, 2006. An expert in atmospheric physics gave an explaination to this phenmonon:

"A very rare phenomenon known as a 'blue sun.' These have been observed from time to time around the world. The most recent widely accepted documentation of a blue sun occurred in September 1950 in Edinburgh, Scotland. A discussion of that event appears in Craig Bohren's book, 'Clouds in a Glass of Beer,' on page 91."

The main cause of 'Blue Sun' is thought to be smoke in the atmosphere. From time to time smoke from farmers burning brush between the camera location and the pyramids' plateau rises to camera level and is apparent on many of our images. Link
