The 'Blue Sun'
PyramidCam captures a live image of the pyramids every 30 seconds. This particular image, saved by Tom Hartlove on December 14, 2006, is one of only a few ever documented occurrences of a blue sun.
Expert in atmospheric physics say that this is 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.
The main cause is thought to be smoke in the atmosphere. From time to time smoke from farmers burning bush between the camera location and the pyramids' plateau rises to camera level and is apparent on many images at PyramidCam.
