A flux rope was released from the Sun's eastern limb as part of an M-flare on 2012 April 16. SOT observed the eruption in the Ca II H line. SOT's high resolution Broadband Filter Imager provides an incredible glimpse into the filamentary structure of the flux rope. The intricate structures developing throughout the SOT field of view highlight the violent interplay between finely threaded magnetic fields and plasma pressure via instabilities and reconfiguration.
