Note:

This CME was difficult to measure in difference imagery due to a bright shock front that was slightly faster than the bulk of the CME. Speeds ranged from 650-800km/s depending on the feature tracked in swpc_cat. StereoCAT measurements yielded similar results. The width of this CME is wider than the more bright portion of the CME due to the portion that is more equatorward adding width to the CME.
