  We investigate the influence of close neighbor galaxies on the properties of
supernovae (SNe) and their host galaxies using 56 SNe located in pairs of
galaxies with different levels of star formation (SF) and nuclear activity. The
mean distance of type II SNe from nuclei of hosts is greater by about a factor
of 2 than that of type Ibc SNe. For the first time it is shown that SNe Ibc are
located in pairs with significantly smaller difference of radial velocities
between components than pairs containing SNe Ia and II. We consider this as a
result of higher star formation rate (SFR) of these closer systems of galaxies.
SN types are not correlated with the luminosity ratio of host and neighbor
galaxies in pairs. The orientation of SNe with respect to the preferred
direction toward neighbor galaxy is found to be isotropic and independent of
kinematical properties of the galaxy pair.
