Evidence has been found for the observation of ultra-high-energy gamma rays from the X-ray binary system 2A 1822-37.1. This source exhibits emission over a broad range of binary phase which appears to change over a period of years. These characteristics are similar to those observed from the UHE source Cygnus X-3. 18 refs.
