Note: Measurement of the brighter, more northern bulk portion based on the source location and best fit between SOHO LASCO C3 and STEREO A COR2 imagery. This event was partially obscured by the pylon in SOHO LASCO C3, and there is a data gap in STEREO A COR2 for which only three frames were available for the measurement. Due to these limitations, there is some uncertainty in the measurement.
