Puppis A is an extended SNR which shows clear signs of interaction with an inhomogeneous interstellar medium, and has an associated neutron star. The SNR has been intensively studied in the radio continuum regime by Dubner et al. (i.e. 1991AJ 101,1466) and in X-rays(Katsuda et al. 2010,ApJ 714,1725, and references therein), while its environment was investigated in molecular and atomic lines by Dubner et al. (i.e.: 1988A&AS 75, 363). The X-ray studies, performed using ROSAT, Chandra and XMM-Newton data, were up to now concentrated in the central and northern parts of the SNR. However, our investigation of data from the XMM-Newton Slew Survey shows that there is significant X-ray emission towards the as yet under-explored southern extent of the remnant, where the radio data suggest an interaction of the local shock front with a molecular cloud. The  correlation X-ray/radio emission is being investigated.
