AB: We report on our efforts to establish reliable markers of CME-driven shocks in white light coronograph images. For this study, we looked at events during the ascending phase of solar cycle 23 when the overall morphology of the white light corona is simple. We isolated events that will be good candidates to drive a shock due to their high velocities (V>1500 km/s). The list includes 15 CMEs. For each event we calibrated the LASCO images and searched for indications of faint sharp fronts ahead of the bright CME front. We report our findings of the analysis of the front morphology, the distant streamer deflections, and the mass and energetics of these events. This work is funded by the LWS TR&T program
