The April 05, 2010 CME erupted from Sun around 09:00 UT on April 03, associated with a flare from NOAA Active Region 11059 (S25 W03). The first signature as seen in ACE is of a shock front at 08:00 UT and a flux rope is observed by ACE at 11:30 UT.

Comment Section

  • Manuela Temmer: we can provide for close to the Sun deprojected height-time, velocity-time, acceleration-time, mass-time/distance plots, as well as some movies (STEREO); have a look under 2010-Apr-03 Event
  • paper http://arxiv.org/abs/1110.0827
  • A well-behaved CME-ICME event (Jie)
  • unsolved question:

explain the magnetic field profile of the ICME; how well do predictions perform?
