Combined UV and hard x-ray observations provide a means to better understanding the temporal and spatial relationship between the energization of the solar corona in flares and the response of the solar chromosphere. In this work, we investigate the evolution of an X1.1 solar flare occurring on 2003 Oct 19 at both UV and hard x-ray wavelengths. This is accomplished through analysis of data from the TRACE and RHESSI spacecraft, respectively. Uncertainties in the TRACE pointing were corrected by coaligning TRACE images with EIT images of the same wavelength for the same time. Coincident RHESSI hard X-ray images were generated in 5keV steps over the range from 10-80 keV. We compare the spatial and temporal evolution of the UV and hard X-ray emissions, for each hard X-ray energy bin, to determine the relationship, if any, between the hard x-ray flare footpoints and the UV continuum emission. We gratefully acknowledge the support of NASA under contract NAS5-02048.
