Note: Very uncertain analysis of the leading edge using only SOHO C2 frames (one coronagraph method in swpc_cat) based on the shape of the northern halo which is almost symmetrical and with the default half width of 45 degrees since the CME is only seen as halo and in one coronagraph. The source being significantly more western (at least 20 degrees to the west of the central meridian), adding to the uncertainty of this analysis.
