Broad and narrow band images and long slit spectroscopy of IC1182 arepresented. The broad band images reveal a distorted morphology with a large,heavily obscured disk-like structure and several knots in the central region.Galactic material, some of it in the form of two tails, is detected well beyondthe main body of the galaxy. The second, fainter tail and several knots arereported here for the first time. The narrow band images show that the galaxyis a powerful emitter. The emission in the main lines extends all over thegalaxy, with plumes and arc-like structures seen in H$\alpha$ at largedistances from the center. The uncorrected H$\alpha$ flux corresponds to3.51$\times10^{41}$ erg s$^{-1}$, 3 times that of Arp 220. The internalextinction deduced from the Balmer decrement is high all along the slit, withE$_{B-V}\approx$ 1. There are no clear signs of nuclear activity and theobserved line ratios can be explained in terms of stellar photoionization. Themetallicity of the gas in the two brightest central knots is low, 0.1Z$_{\odot}$ and 0.06 Z$_{\odot}$ respectively. In the main body of the galaxy,besides the reported knots, the distribution of the ionized gas resembles thatof an inclined disk about 12 kpc in size. The rotation pattern is complex andcorresponds to two identifiable disk galaxies with observed rotation amplitudesof 200 \kms and 100 \kms respectively. The data presented here indicate that IC1182 is a high luminosity starburst system, involving two systems in theprocess of merging, with two tidal tails emerging from the central region ofthe galaxy.Comment: 15 pages, 9 figures.
