Abstract

An emission nebula has been discovered near the core of the Local Group dwarf elliptical galaxy NGC 185. On the basis of the high intensities of forbidden emission lines of S II and N II relative to hydrogen alpha, it is concluded that the nebula is shock heated and most likely a supernova remnant. This feature is possibly related to the existence of a Population I component in NGC 185. The ratios of forbidden N II to S II emission in the nebula suggest the interstellar medium in NGC 185 is at most moderately metal poor (less than about 1/3 the metal of the sun).
