Note: Triangulated measurment between SOHO LASCO C2/C3 and STEREO COR2A, with good confidence in a matched far-sided fit around W120-W130 despite the lack of source observation in SDO AIA, GOES SUVI, or STEREO A EUVI. The brighter bulk of the front in SOHO imagery is notably dimpled inwards, but the outer edges were sharp enough to track the leading edge.
