| Abstract: | Balloon observations of the X-ray source Sco X-1 carried out in November 1978 have revealed a thermal spectrum withkT?7 keV in the 20–60 keV energy band. In addition, there was evidence of a high energy component, possibly variable, above ～50 keV. The spectral form of this component could not be determined but was hard with a 60 keV flux of ～10?4 photons (keV cm2 s)?1. |
