Investigating the Temporal Behavior of Localized UV and Hard X-ray Emission in Large Solar Flares
Abstract
While many studies have related the timing of localized UV emission tospatially unresolved hard X-ray lightcurves, few have compared the timeprofiles of spatially localized UV and hard X-ray sources. In this workwe present a study of large two ribbon flares observed with RHESSI andTRACE in which multiple hard X-ray sources develop along the ribbonsduring the course of the flare. Our preliminary findings indicate thatlate in these multi-burst events, the UV emission onset precedes theX-ray emission with delays on scales of seconds. These observations havepotential implications for particle production and transport mechanismswithin complex flares.
