Search for ultra-high-energy gamma-rays from SN 1987A.

Supernova 1987A has given a unique opportunity to test for supernova acceleration of particles to energies above approximately 10 to the 15th eV. The accelerated cosmic rays should interact with local supernova shell material to produce UHE gamma-rays detectable with air shower arrays. A search of data recorded by the Buckland Park air shower array over the first full year since the detection of SN1987A is reported, setting an upper limit of 7.7 x 10 to the 40th ergs/sec to the proton luminosity of the source.
