Note:

Shock measurement of a wider and faint, but noticeable feature traveling with the bulk front (which tracks with the observed EUV wave in SDO). Made with only SOHO LASCO C2/C3 imagery due to a data gap in STEREO COR2A, and as such some variance in the true lat/lon may be noted given the single coronagraph measurement. Initial lat/lon were based on the observed EUV source, and found a good fit near this with some southward deflection.
