    Abstract

    Evidence for TeV gamma-ray emission from 1E2259 + 586 has recently been reported by the Durham Group (Brazier et al., 1990). Evidence suggests that the source is a steady gamma-ray emitter, with a flux an order of magnitude higher than that of the Crab Nebula (Weekes et al., 1989). The Whipple Collaboration observed 1E2259 + 586 for a total of 80 H between November 1985 and November 1988 using the atmospheric Cherenkov imaging technique. These observations, were analysed for evidence of periodic emission at the fundamental and second harmonic of the X-ray period. No evidence for gamma-ray emission from this source is found.
