I find this interesting. I have been doing some research and found and explanation given by nasa for similar looking images at http://stereo.gsfc.nasa.gov/artifacts/artifacts_debris.shtml
although it states that they are caused by debris passing by the field of view of the spacecraft which houses the cor1 telescope, noting that the same object may appear more that time in the same image due to the image being a composite of other images. In this case though the ojbect is not seem multiple times in the same image but in fact stays stationary for days and is still present in the latest images available to view at http://stereo.gsfc.nasa.gov/cgi-bin/images
this would suggest it is not caused by debris passing by the camera. To me the rational reason would be debris stuck to something, either inside the camera or spacecraft or on the exterior of the craft.
