In April 2001 SN1993J was observed with both the PN and MOS cameras of the XMM-Newton observatory , resulting in about 7 \times 10 ^ { 4 } s of acceptable observation time .
Fit results with both the PN and MOS2 camera spectra studying different spectral models are presented .
The spectra are best fitted in the energy range between 0.3 and \sim 10 keV by a 2-component thermal model with temperatures of kT _ { 1 } = 0.34 \pm 0.04 keV and kT _ { 2 } = 6.54 \pm 4 keV , adopting ionization equilibrium .
A fit with a shock model also provides acceptable results .
Combining the XMM-Newton data with former X-ray observations of the supernova , we discuss the general trend of L _ { x } \propto t ^ { -0.30 } and the bump of the X-ray light curve as well as former and recent spectral results in the light of the standard SN model as first proposed by Chevalier in 1982 .
