Note: Triangulated measurement between later frames of SOHO LASCO C3 and two available, low quality running difference images of STEREO A COR2. The CME deflects northward as it travels through LASCO C2 to C3 so later frames capture the final width and direction better. STEREO A COR2 imagery becomes sparse over this CME leading to lower quality running difference imagery that is usable.
