Scientific paper

The observations of supernova 1987A, performed by High Energy X ray Experiment (HEXE) on board of the Mir-Kvant module, are reported. A total observation time of 530,000 s was spent on that target, and data are available from day 144 to 843 after the outburst. Comparison with published results, data from four detectors, and improved background subtraction method are considered. A final energy calibration is established. Hard x ray flux from SN 1987A are discovered. X ray light curves are presented in three energy bands, extending the time coverage to June 1989. The new results confirm the results published.
