Note:

Analysis only using SOHO LASCO C2/C3 imagery, with only the closest few C3 frames available for use as the front fizzles fast. I found difficulty trying to triangulate this front between SOHO LASCO C2/C3 and STEREO COR2A at all possible longitude ranges--so this measurement assumes a source longitude of W70 in line with the likely source filament. Includes both "bumps" of the front in one cone, using the sides to capture the entire front.
