Note: Approximate analysis based on the fit with two coronagraphs (SOHO LASCO and STEREO A COR2) and supported by the range of possible longitudes (based on the CME appearing northeast in LASCO and northwest in STEREO A). This analysis is based on the clearer second front directly following a messier first front of the CME, as they appear in both coronagraphs.
