We simulate the 12 May 1997 interplanetary coronal mass ejection (ICME) event with a numerical 3-D magnetohydrodynamic (MHD) model, in which the background solar wind is determined from the SAIC and WSA coronal models, and the transient disturbance from the so-called cone model. We launch the same ICME-like, over-pressured plasma cloud into the background solar wind derived from various models including daily-updated coronal maps. We found that improved agreement with the observations is achieved when the maps are artificially modified to simulate the rapid displacement of one of the coronal hole boundaries after the CME eruption. We illustrate that multi-point temporal profiles of solar wind parameters and multi-perspective synthetic white-light images can be used to differentiate between various event scenarios that might be otherwise difficult to distinguish using single-point observations only.
