Abstract
We present the results of a deep ROSAT HRI observation of the supernova rem nant Kes 32 and the possibly associated pulsar PSR B1610-50. The supernova remnant shows strongly energy dependent complex structures in a comparison with the ASCA GIS and ROSAT PSPC data with low foreground absorption (NH si milar to 5 X 10(21) cm(-2)). The pulsar is not seen in the HRI image indica ting a high absorbing column density (N-H;greater than or similar to 5 x 10 (22) cm(-2)) along the line of sight, making the physical connection betwee n Kes 32 and PSR B1610-50unlikely. The elongated structure south of the pul sar, interpreted as a pul sar jet, might be an unrelated foreground emissio n.
