摘要：

We present gamma-ray observations of SN1987A in the energy range from 150 keV to 1 MeV carried out on June 19, 1988, on-board a stratospheric balloon with two NaI(T1) detectors (600 cm2 total area). The telescope incorporated a passive collimator and was mounted on a stabilized platform which allowed observations with a pointing accuracy of approximately 2-degrees in azimuth. The flight altitude was about 5.5 mb and the total observation time was 6 hours, divided between source and background. The 2 sigma upper limits for the continuum are 2.45 x 10(-5) and 5.42 x 10(-6) photons cm-2 s-1 keV-1 in the 0.5 to 0.30 MeV and 0.30 and 1.00 MeV energy bands, respectively.
