Comment Section

  • Manuela Temmer: we can provide for close to the Sun deprojected height-time, velocity-time, acceleration-time, mass-time/distance plots (direction E7) as well as some movies (STEREO); have a look under 2011-Feb-15 Event
  • A "big" event of having everything: 2012/02/15 X2 flare, coronal dimming and wave, fast halo CME in LASCO, strong signature in COR2, and high magnetic field in the ICME sheath region as seen in in-situ (Jie).
  • Question: on 2012/02/14 (18 UT), there was an Earth-directing CME as seen from C2 and CORs. Did this halo CME also reach the Earth, in addition to the one originated on 2012/02/15 (02 UT). Is CME-CME interaction involved in these two events? (Jie)

In-Situ Data

A combination of SWEPAM and MAG data from the ACE Satellite:

The blue lines are an approximation of the CME cloud and the red line denotes the shock.
