We report on the latest results from an analysis of data on Cygnus X‐1 as collected by the COMPTEL experiment on the Compton Gamma‐Ray Observatory (CGRO). COMPTEL detected the source around 1 MeV during two separate one‐week observations in 1991. The measured flux levels indicate variability on a time scale of weeks. The results also indicate flux levels which are well below the levels reported by some investigators for an excess of emission in the energy range ≥1 MeV.
