Before you call something "fucking retarded" do yourself a favor and spend 15 secs on a search engine so you don't make yourself look like an uneducated blowhard.

scientific american say:

"Key to space weather forecasting is the distinction between solar flares and CMEs. If a flare is the muzzle flash of a gunshot, the CME is the bullet. The x-rays and extreme ultraviolet radiation from flares reach Earth at near light-speed, and by the time we observe them, their effects—such as disruptions of high-frequency radio signals or satellite navigation systems—are already being felt."

in case you don't know its the "extreme ultraviolet" that would blind you.
