A global MHD simulation of an event with a quasi-steady northward IMF Merkin, V.G., Papadopoulos, D., Lyon, J., Anderson, B. We show results of a global MHD simulation, using the Lyon-Fedder-Mobarry (LFM) model, of an event previously examined using data from Iridium spacecraft observations as well as DMSP and IMAGE FUV data. The event is chosen because of the steady northward IMF sustained over a three-hour period during 16 July 2000. The Iridium observations showed very weak or absent Region 2 currents in the ionosphere, which makes the event favorable for global MHD modeling, despite the fact that it occured on the day after the "Bastille Day" storm, and there was a significant remnant ring current in the magnetosphere as indicated by a relatively high Dst index. Here, we compare the ionospheric field-aligned current and electric potential patterns with those recovered from Iridium observations. Particular attention is paid to a comparative analysis of the Pointing flux and the energy flux of precipitating particles, and the verification of the simulated particle flux against IMAGE FUV observations, that is used to validate the LFM precipitation model during weak driving. _______________ Fall Meeting, American Geophysical Union, San Francisco, U.S.A., 5-9 December 2005
