Comment Section

  • This is a varSITI campaign event for ISEST and SPeCIMEN.

At the Sun the event had an M1.1 flare, erupting filament, type IV radio burst, fast halo CME. At Earth a shock, possible MC, SEP, and strong storm, Dst=-132. A TB case. Modeled by C-C Wu. [Added by D. Webb]

  • Depressed density and temperature as well as decreasing velocity are indicative of a flux rope, but with the weak magnetic field it may just be the flank passing through the Earth. Clear shock signatures in temperature and velocity and total B, more of a gradual increase in density. (Hess)

"This event must have impacted Messenger at Mercury, which is roughly 30 west of the Sun-Earth line." (Moestl)
