Description
The black hole candidate Cygnus X-1 was observed in the hard X-ray - soft gamma-ray energy range by the Miso telescope on two different occasions: in September 1979 and May 1980. Two hard X-ray states of the source have beem measured: in 1979 the observed spectrum confirms the superlow state measured in the same period by the HEAO-3 satellite, while in 1980 the Miso X-ray data are consistent with the so-called low state of Cygnus X-1. In both occasions, no gamma-ray excess has been observed above 200 keV. 9 references
