AB: We investigate the temporal and spatial relationship between filament eruptions and the production of hard X-ray emission using spatially resolved high cadence data from TRACE and RHESSI. In particular, we focus on comparing the characteristics of the hard X-ray production in `successful' and `failed' filament eruption cases. Our preliminary findings indicate even failed eruption events can generate significant energy release and hard X-ray emission with the hard X-ray production apparently correlated to the rate of expansion of the filament. The spatial distribution of the hard X-ray emission, while depending upon the overall strength of the event, also depends on the evolutionary behavior of the filament as it erupts, e.g. loop-like versus "zipper"-like.
