Cosmic rays impact the sensors, impart their electrical charge, and create such streaks. Please look it up - it's one of the reasons satellites and space ships have radiation shielding. The original photo was not taken offline (of course).

In fact, anyone bothering to look will find all of the stereo behind EUVI 195 images for that day here: http://stereo.gsfc.nasa.gov/browse/2011/.../195/2048/
And, of course, the artifact was not there the entire day.
