Note:

Updated SHOCK measurement using potential source location from STEREO A EUVI 304/195. There is a higher level of uncertainty with this analysis due to limited triangulation ability as well as the unique shape of the CME front. This analysis tracks the furthest out portion of the shock (the "nose") of the CME and includes most of the shock that is more in the ecliptic plane, however this measurement also includes unavoidable empty/dead space due to the overall shape of the shock front and the restrictions of the SWPC_CAT measuring tool.
