Scientific paper

Results of observations of Her X-1 made on 17 April 1983 using the array of four telescopes of the Dugway Very High Energy (VHE) gamma ray facility are reported and discussed. A significant three-minute outburst of VHE gamma rays which had a 1.24 sec periodicity was detected. This outburst occurred 35 days before an observed X-ray turn-on. The gamma ray luminosity during the outburst was of the same order as the X-ray luminosity. Together with the coincidence in time, this suggests a connection between the mechanisms giving rise to the gamma ray outburst and the X-ray turn-on. Subsequent monitoring of the source during a period when the X-ray flux was decreasing yielded some evidence of much weaker pulsed gamma ray activity at the pulsar period. A possible similarity between this system and Cygnus X-1 is noted.
