I saw reports yesterday that the Solar Dynamics Observatory recorded a huge coronal mass ejection. Today I checked Ian O'Neill's blog to see what happened. Pretty lights! Thanks earth, for keeping us from being overly radiated right now.
"By measuring the number of protons and the intensity of the magnetic field fluctuations, space weather scientists are able to deduce that the CME launched from the sun early on Sunday morning arrived at the Earth on schedule."
I like that they confirmed the speed of light is still what we think it is.
