Comment Section

  • Very Powerful, fast CME eruption from NW section of the disk around 04:00 on the 23rd, that sent a shock, sheath region and possibly a flank of CME to the Earth. Strong M Class flare from AR 11402, but there were a number of active regions nearby that could have played a role in the eruption. LASCO images and the plasma data gap in ACE indicate strong SEP production. (Hess)
