Abstract
Heavy quark energy loss in a hot QCD plasma is computed taking into account the competing effects due to suppression of zeroth order gluon radiation below the plasma frequency and the enhancement of gluon radiation due to first order medium induced Bremsstrahlung. The results suggest a surprising degree of cancellation between the two medium effects for charm quarks and provides a possible explanation for the null effect observed by PHENIX in the prompt electron spectrum in Au+Au at $\surd s=$ 130 AGeV.
