E. ; Boldt, E. A. ; Holt, S. S. ; Serlemitsos, P. J. Abstract Observations made with the Solid State Spectrometer (SSS) aboard the Einstein Observatory confirm Kepler's SNR as an X-ray source with an intensity between 1 and 3 keV of 7.2 x 10 to the -11th ergs/sq cm s. The X-ray spectrum is similar to those of Cas A and Tycho, with strong line emission from the helium-like species of Si, S, and Ar. Direct comparisons to Tycho's SNR suggest a distance to Kepler's SNR of not less than 5 kpc.
