Scientific paper

SN1987A was observed on 19th April 1987 with a combined high energy γ-ray and hard x-ray payload, flown on a stratospheric balloon from Alice Springs, Australia. The γ-ray detector, sensitive in the energy range 50-500 MeV, was an optical spark chamber with 400cm2 area, a field of view of 60° FWHM and a time resolution of 10 μs. The counting rate profile at ~2.2 mb float altitude has lead to a 3σ upper limit to the steady γ-ray flux of 7×10-4 ph cm-2 s-1 in the 50-500 MeV range. This upper limit is compared to our predictions for the time profile of γ-ray emission from SN1987A resulting from pulsar acceleration of particles to cosmic ray energies.
