In April 2001 SN1993J was observed with both the PN and MOS cameras of the XMM-Newton observatory. A 2-component thermal emission model assuming ionization equilibrium provides a good fit to the spectrum in the 0.3 to 11 keV energy band, but fits to shock models show also acceptable results. The development of the X-ray temperatures over the first 8 years after the explosion is discussed in the light of the standard SN model. The long term X-ray lightcurve shows a general decline of the luminosity with L x α t −0.30.
