Comment Section

  • A slow CME swept up by a CIR (J. Zhang)
  • Not sure about the source CME (1) 04/19 15 UT CME, or (2) 04/18 03 UT CME (also other halo CMEs on 04/18); need further work on this.
    • It is always a problem of identification when a slow ICME occurs.
  • In Moestl's list, CME (1) on April 19 16:24 (first image in COR2A) is the source for the ICME
