Nacreous clouds ten miles above the earth. Taken at McMurdo Antarctic research station by Chad Carpenter.
Fire rainbows are the rarest of all naturally occurring atmospheric phenomena. For a fire rainbow to occur, cirrus clouds must be 20,000 feet in the air with the precise amount of ice crystals, and the sun must hit the clouds at 58 degrees
MINOR MAGNETIC UNREST: A CME swept past Earth on July 13th. Its impact was gentle, but the CME's wake is unsettling the geomagnetic field. Last night, July 14-15, magnetometers registered a minor (Kp=5) geomagnetic storm for nearly six hours. High-latitude sky watchers should remain alert for auroras as CME effects subside.~they said it was | http://exploringuniversecollections.blogspot.com
