Abstract
We have observed IC 5283, a neighbor of the well-known Seyfert galaxy NGC 7469, using the 2.6-m tel at Byurakan ObservatorY with interferenc e filters in the continuum and at Halpha and [N II]lambda 6584. We con ducted a comparative morphological study of the galaxy, and used the [ N II]Halpha ratio to calculate the nitrogen abundance distribution emp irically. We found that the galaxy has two spiral arms, with differing rates of star formation; that the radial distribution of hydrogen abu ndance and its mean value are typical of late-type spirals; and that w e could detect no azimuthal variation in the nitrogen abundance or var iation along a spiral arm.
