Abstract:
The more advanced our society becomes the more reliant it is on its infrastructure. Hydro Quebec blackout in 1989 was a very clear indication that our infrastructure is very susceptible to extreme space weather events. We present numerical output from OpenGGCM-RCM-CTIM model that is driven by the real solar wind data from solar monitors during the disturbed solar wind times. The model output will be compared with DMSP data to establish a baseline for the open-closed field line boundary. The known events will be scaled up to STEREO-A’s July 23, 2012 CME level of intensity with increasingly stronger solar wind drivers. We will show the comparison between open-closed field line boundary location for each case.
