AB: We present here the results of our latest simulations of the magnetosphere and ionosphere during the period from October 29 to November 1, 2003. These results supersede our initial attempt to simulate the events of this period at the Spring Joint Assembly. We found then the extreme solar wind conditions during this period challenged not only our simulation, but also the solar wind observations. Our initial simulation, which showed many interesting features, was driven using the best solar wind values available from ACE at that time Since then, comparison of solar wind observations from ACE, GEOTAIL, and WIND, have led to a better understanding of the solar wind parameters. Using a synthesis of the ACE and GEOTAIL plasma data, we have using the Lyon-Fedder-Mobarry (LFM) global MHD code to simulate both the magnetosphere and ionosphere, with progressively larger grid resolutions. We present as well results from the CMIT model, in which the ionosphere of the LFM is replaced by the NCAR Thermosphere Ionosphere Nested Grid (TING).
