Observations made with the Solid State Spectrometer (SSS) aboard the Einstein Observatory confirm Kepler's SNR as an X-ray source with intensity between 1 and 3 keV of 7.2 x 10/sup -11/ ergs cm/sup -2/ s/sup -1/. 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 > or =5 kpc.
