The X-ray emission of supernovae is a young field with relatively little data. X-rays provide information about the circumstellar ejecta as the outgoing shock runs into matter from previous phases of mass loss. A reverse shock is created which generates low-energy X-rays (~1 keV) while the outgoing shock generates harder events. The X-rays probe the circumstellar matter and are expected to provide measures of abundances in spectral lines. The X-ray light curve (LC) additionally provides a measure of the matter distribution (Ref for SN: Schlegel 1995, Reports on Prog in Physics, 58, 1375). The radio LC of SN1979C has been interpreted as revealing waves of mass loss (Weiler et al. 1992, ApJ, 399, 672) from the progenitor. No other SN has shown such behavior prior to the recent increase in the radio LC of SN2001ig. We expect the hard and soft X-rays to behave differently, directly testing shock/reverse shock theory.
