We present images of the peculiar galaxy Arp 10 which reveal two rings of concurrent star formation. Apart from a bright ring visible on early photographs of the system, an even brighter inner ring of HII regions is found within the nuclear bulge of the galaxy. A very faint ring arc of HII regions is also seen associated with a third outer ring or shell and a small companion galaxy is observed on the minor axis of the system. An investigation of the Hα fluxes in the rings reveals a sharp transition from a low Hα surface brightness to a high level when the surface density of the R-band light in the rings exceeds 21.5 magarcsec(-2) . The results suggest that the star formation rate in the rings exhibits a threshold-type dependence on ring continuum surface density. We examine a possible collisional nature of the system and we compare it with our recent studies of other ring galaxies.
