Another big flare and associated CME caught by the SDO last Thursday.
"Just as an active region rotated into view, it unleashed a large (X1.4 class) solar flare (Sept. 22, 2011) as well as several smaller flares and a significant coronal mass ejection. Predictions are that the storm will likely not impact Earth. Following the bright flare, one can see brilliant coils of magnetic field lines regrouping themselves. Images were taken by NASA's Solar Dynamics Observatory in extreme ultraviolet light."
