Note:

There's a higher degree of uncertainty with these parameters due to the limited available imagery in the STEREO A and SOHO LASCO C3 coronagraphs. The longitude may vary by +/- 20 degrees depending on the fit. There could also be a wider shock portion that was not included in this measurement due to faintness and limited imagery.
