Abstract : Stellar fluxes of the order of (10 manoergs/sec A(cm squared)) for 10-eV photons have been observed for several bright ultraviolet emitting stars. These observations were made from the OGO-VI scanning Lya experiment whose resonance absorbtion filter suppressed the strong HLya airglow, enabling weak external enhancements to be observed. Five separate orbits of data revealed point-source enhancements. Observation with an SrF2 background light filter established that less than 10% of the observed signals could be at spurious wavelengths. (Author)
