  • The gamma-ray spectrometer (GRS) on NASA's Solar Maximum Mission satellite (SMM) has observed a significant (>5δ) net line flux at ˜847 keV in the background-subtracted spectrum of SN1987A—accumulated between 1 August and 31 October 1987. This is the energy of the strong gamma-ray line from decay of 56Co, which was predicted1,3 to be seen from supernovae. The inferred average line flux during this period is ˜(1.0±0.25) x 10−3 photons cm−2 s−1 at an energy of 843 ± 5 keV. This feature cannot be… CONTINUE READING
