Comment Section

==Perhaps due to the location of the spacecraft, I cannot see anything in STEREO to cause the ICME. I also see no significant Halo CMEs in LASCO during the days leading up to the in-situ signature. The Ying Liu paper listed in the reference section dealt only with the in-situ data, so I am not sure about the CME connection for this event. (Hess) ==three density peaks seemed to correspond to (1) sector boundary, (2) small ejecta, and (3) CIR interface, respectively (Jie Zhang)
