title: Spectrum and Distance of Source Sco XR-1.
abstract: In a broad sky survey for x-ray sources in the 44-to 60-A range only Sco XR-1 was detected. The spectral evidence indicates that Sco XR-1 may lie within a few hundred light-years of the sun. Its spectrum appears to be complex possibly a mixture of thermal sources at different temperatures or of thermal and nonthermal components, as has been predicted for an active neutron star with an associated corona or magnetosphere.
