Abstract
Deep ROSAT PSPC and HRI observations of the nuclear starburst, UV flat spectrum spiral NGC 6217 reveal a jet-like X-ray filament extending out 2$\farcm$7 (18.8 kpc) to the SW of the galaxy. Radio images of NGC 6217 show an extent in the same direction, giving further evidence for a one-sided X-ray jet interpretation of this feature. Its X-ray spectrum is harder than that of NGC 6217 and the luminosity in the 0.5-2.0 keV band is ~1.7 $\times 10^{39}$ erg s-1. We compare our findings to parameters of other X-ray jets from other active galaxies. We also give positions of a total of 91 X-ray sources detected in the field to a limiting 0.5-2.0 keV flux of ~2.2 $\times 10^{-15}$ erg cm-2 s-1 and propose optical and radio identifications. Some of these sources have been identified in the RIXOS program.
