Note: Measurement using the location of the source seen in UV imagery of the Earth-facing disk and the best fit between SOHO LASCO C2 and STEREO A COR2. The full leading edge and a small interior flux rope are both faintly visible in C2, but this CME is only tentatively seen as an extremely faint feature for two frames in STEREO A COR2, so there is some uncertainty with this measurement. The best fit parameters match well with the approximated source location if taking into account some southern deflection, though, which increases confidence a bit. Leading edge is too diffuse to track in SOHO LASCO C3.
