Description

An attempt was made to measure soft X-rays from SN 1972E. The resulting upper limit shows that 19 days after discovery, the X-ray luminosity was not greater than 10 percent of the optical luminosity. Measurements of the background in the surrounding region show that a localized enhancement, observed previously, dominates the diffuse flux in this area. Two maps give the spatial dependence of the diffuse flux in the energy ranges 0.20.6 keV and 0.61.6 keV. Subject headings: supernovae - X-rays
