Symbiotic stars are binary systems composed of a hot white dwarf and a cool red giant star embedded in a circumbinary nebula. Roughly half of all symbiotic stars exhibit two strong, broad Raman scattered emissions at 6825 Å and 7082 Å. These lines result from the inelastic scattering of far ultraviolet O VI photons of 1032 Å and 1038 Å, respectively, on the ground state of H I. Raman scattering provides an important diagnostic for velocity fields in the nebular material surrounding the hot component. Additionally, it can be useful for examining mass loss rates in the cool component. The symbiotic stars RR Tel and V1016 Cyg have recently been shown to exhibit weak Raman scattered He II lines at 4851 Å and 6545 Å. These lines result from Raman scattering of far UV He II photons on the ground state of H I. We report the possible detection of a weak Raman scattered He II line at 4851 Å in the symbiotic nova HM Sge and its implications.
