Note:
Approximate analysis of the messy, two-lobed bulk front of this CME, based on the fit with three coronagraphs (STEREO A COR2, SOHO LASCO and GOES CCOR-1). There is clear northward deflection from the source location of the M-class flare (N14W13) but the associated erupting filament seems to originate a bit to the west from the flare location and is then seen deflecting northwardly, so the coronal signatures generally confirm this analysis. The half-width of the CME is based on later imagery in STEREO A COR2, as in coronagraphs there is/are later, wider, lobe(s) of this CME that seem to be integral part of it.
