Abstract (from CDS):

Detailed BVRI-Hα photometry has been obtained for the ring galaxy HRG 2302. This is probably a still interacting system which shows two principal components: the target, which is a knotted ringed-disk, and the intruder, an elongated galaxy with two substructures probably caused by the interaction. The existence of HII emission regions is suggested by Hα images and medium dispersion spectra of the three brightest parts of this system. Analysis of a color-color diagram suggests recent star formation, in agreement with the behavior of interacting galaxies with nuclear emission. HRG 2302 has been previously classified as a Polar Ring galaxy (Faundez-Abans & de Oliveira-Abans, 1998A&AS..129..357F), but we have reclassified it as Elliptical-Knotted, based on the morphological substructures found. This work reveals, for the first time, the existence of at least 15 fainter galaxies in the field within ∼4' around HRG 2302, giving positions and integrated standard magnitudes for all of them.
