In this work, we investigate, for a number of solar flares, the evolution of both UV hard x-ray emission as observed by TRACE and RHESSI, respectively. The spatial resolution of these two instruments provides an unprecedented capability to study the individual source regions producing the observed time profiles in these events. Confirming earlier results, it is found that individual bursts in the hard X-ray time profiles are correlated with the unresolved UV emission. However, the temporal evolution of individual sources provides a deeper insight into the flare energization process. We report a number of results: 1) the UV-to-UV temporal correlation analysis allows us to identify sources which exhibit similar time profiles and therefore may indicate conjugate footpoints of a large coronal loop, 2) the UV emission is distributed over a wider area than the hard X-ray emission, 3) the bulk of the hard X-ray emission would seem to be related to a different structure within the flaring volume but sharing a common footpoint with the UV emission, and 4) the temporal and spatial behavior observed would seem to indicate an interacting loop scenario for the flares considered.
