Note: CME is a beautiful loop with one piece that protrudes out on the left-hand side. Measurement was made by fitting the lemniscate to the 'perfect' loop, then setting the leading edge to be halfway between the loop and the front of the protruding piece. Measurement was made using source location of the filament with adjustment for apparent southeastern deflection seen in UV imagery of the Earth-facing disk, along with best fit between coronagraphs SOHO LASCO and STEREO A COR2.
