Scientific paper

Hard X-ray emission from SN1987A in the energy range from 20-350 keV has been observed by the HEXE and Pulsar X-1 instruments on the MIR-KVANT Roentgen observatory. After the first observation of the hard X-rays on August 10, 1987 the SN became the main target of the observatory. The measured photon spectrum is extremely hard with a power law index of about 1.4. At lower energies the spectrum seems to become flatter and there is an indication of a cut off below 25 keV. The luminosity in the above energy band is 2×1038 erg/s. The flux does not show a significant variation between August 10 and the end of November.
