The energy released in a solar flare is partitioned between thermal andnon-thermal particle energy and lost to thermal conduction and radiation over abroad range of wavelengths. It is difficult to determine the conductive lossesand the energy radiated at transition region temperatures during the impulsivephases of flares. We use UVCS measurements of O VI photons produced by 5 flaresand subsequently scattered by O VI ions in the corona to determine the 5.0
