Note:

One-spacecraft (SOHO) bulk measurement considering the full-width of the CME using an approximate but not ideal source longitude behind the western limb. The true source of the eruption appears to be between 100 and 105 degrees, but the CME width makes it difficult, if not impossible to reliably fit the CME bulk to this longitude. While it fits the CME shape, a front-sided longitude was not chosen since it will greatly overestimate Earth-directed impacts. No STEREO A COR2 imagery at this time.
