AB: On March 23, 2007 the 5 THEMIS spacecraft observed the onset of a substorm while located in the dusk flank of the magnetoshere. The substorm was also observed in ground-based data and in Polar UVI images. Using Wind data to drive the OpenGGCM we conducted a simulation study of this substorm. The simulation clearly shows the substorm characteristics, such as the current wedge and expansion of the aurora. In this paper we compare the OpenGGCM simulation with observations, address the magnetic mapping between THEMIS and the auroral features, and investigate whether this substorm was triggered by a sharp northward turn of the IMF.
