On June 15th, sky watchers around Iran witnessed a strange and luminous cloud in the night sky. "I have never experienced a similar phenomena," reports veteran astronomer Babak A. Tafreshi of Tehran. Observing alongside two other astronomers, Oshin Zakarian and Pouria Nazemi, he took this picture:

"The object started out patchy, shapeless and dim; it quickly brightened and formed a blue-tinted cone with a nose of magnitude -2 or -3," he says. The cloud raced across the sky "moving about 20 degrees per minute." More images: #1, #2, #3, #4, #5, #6.

"It was shining blue and moving fast," agrees Amir Hossein Abolfath, another witness from Tehran, who snapped this picture. "Twenty minutes after I saw it, my friend Asghar Kabiri saw the same cloud 900 km away from Tehran in Sa'adat shahr."

The cloud resembles the explosion of a partially-fueled Russian Briz-M rocket booster over Australia in February 2007. Likewise, this could be the re-entry and explosion of a derelict rocket, or it may be related to the June 15th launch of an Atlas rocket from Cape Canaveral. Stay tuned for more information.
