We revisit the "failed" filament eruption of 2002 May 27, first studied in detail by Ji et al. investigate temporal and spatial relationship between dynamics production hard X-ray emission using spatially resolved high-cadence data from TRACE RHESSI. confirm presence a source corona above prior to main activation phase identify second coronal source, not considered earlier studies, that occurs under apex during erupting when is clearly strongly kinked. argue this implies ongoing magnetic reconnection current sheet formed via kink instability resulting interaction two adjacent legs underneath writhing filament, agreement with simulation results. The energy release site has important implications for models solar eruptions.
