I went back into the spaceweather archives to get the text -- here is what is says (it was from August 18th):
"Every 10 milliseconds somewhere on our planet a bolt of lightning plunges down from the clouds and strikes Earth. A few nights ago in the Mojave Desert, JPL astronomer James W. Young photographed a magnificent strike:
If this lightning bolt was like most, it heated the air around it to ~20,000o C or three times hotter than the surface of the sun. (No wonder lightning starts so many wildfires.) The bolt itself was lit by a thousand billion (1012) watts of electrical power. If you see such a display, take the picture, then take cover!"
