[en] The MSSL 0.5-1.5 keV X-ray telescope on Copernicus has examined several features of previous X-ray maps of the Cygnus Loop. We derive fluxes and spectra for the north and northeastern filamentary regions, together with an upper limit for the X-ray flux from the radio source labeled CL4 by Keen et al. Correlation between the X-ray and radio structure is established
