We analysed a Fabry-Pérot cube of the interacting pair of galaxies Arp 70 which was obtained from a public repository of FP data. On the larger galaxy Arp 70b we found two different types of outflows, one in the centre and the other associated with a giant HII region in the arm region. The central outflow is especially prominent, with the flux of the secondary peaks being similar to that of the main peak. We used an archive fibre spectrum from SDSS to determine that the centre of the galaxy housed a LINER which is the origin of the outflow. We also confirmed the detection of the outflow in the SDSS spectrum in Ha and [NII]. Using the FP cube we estimated the shape of the outflow which comprises two cones of expanding material, one approaching and the other receding from us, and used this to estimate the physical properties of the outflow, finding energies of order 10^57 erg and masses of order 10^8 Mo.
On the giant HII region we found a similarly gigantic expanding superbubble with a diameter of ~5 kpc. The bubble has an energy of order 10^54 erg and a mass of about 4·10^7 Mo. We discuss the possibility that both of these features are the result of the interaction between the pair of galaxies.
