Note:

Plane of Sky measurement of faint front using five frames of SOHO LASCO C2 running difference imagery. This faint leading edge becomes diffuse before reaching the edge of the SOHO LASCO C2 field of view. Obstructed by pylon in GOES CCOR-1. Not discernable in STEREO A COR2 white light and running difference, due to faintness.
