N2  - Observations have been made with the Buckland park air shower array over a two-year period from June 1984. We have examined events from the directions of six binary X-ray systems to search for any periodic component associated with ultra-high-energy gamma-ray emission above a threshold energy of -9xl014 eV. No statistically significant excess has been found and upper limits to the individual fluxes are presented.
