We map out the low momentum direct photon observables and present the results of the measurements in Au+Au collisions at sqrt(sNN ) = 62.4 GeV and s N N = 39 GeV, using data samples of externally converted photons. The observed direct photon excess yield at these low energies can be interpreted as a sign of thermal radiation from the Quark Gluon Plasma, in addition to the PHENIX previous result.
