Blow Out

December 11, 2012
A relatively small coronal mass ejection blew out from the Sun over a 10-hour period (Dec. 4-5, 2012). There was a rounded crown arcing over the active region before something triggered the event that blew it into space. The looping coils on the surface that followed are particles spiraling along magnetic field lines that are reconnecting with each other. The images were taken in extreme ultraviolet light in the 171 Angstrom wavelength (colorized red).
