We investigate the influence of close neighbor galaxies on the properties ofsupernovae (SNe) and their host galaxies using 56 SNe located in pairs ofgalaxies with different levels of star formation (SF) and nuclear activity. Thestatistical study of SN hosts shows that there is no significant differencebetween morphologies of hosts in our sample and the larger general sample of SNhosts in the Sloan Digital Sky Survey (SDSS) Data Release 8 (DR8). The meandistance of type II SNe from nuclei of hosts is greater by about a factor of 2than that of type Ibc SNe. The distributions and mean distances of SNe areconsistent with previous results compiled with the larger sample. For the firsttime it is shown that SNe Ibc are located in pairs with significantly smallerdifference of radial velocities between components than pairs containing SNe Iaand II. We consider this as a result of higher star formation rate (SFR) ofthese closer systems of galaxies. SN types are not correlated with theluminosity ratio of host and neighbor galaxies in pairs. The orientation of SNewith respect to the preferred direction toward neighbor galaxy is found to beisotropic and independent of kinematical properties of the galaxy pair.
