Abstract
SPINRAD et al.2 have suggested that the infrared object Maffei 1 is the nucleus of a nearby elliptical galaxy about 1 Mpc away. Oort2 has pointed out that observations from Westerbork do not show any radio source near the nucleus of Maffei 1, but there are three radio sources in the field around Maffei 1: 3C 69 and two unknown sources, here named as 01 and 02. Assuming these unknown sources to belong to a galaxy 1 Mpc away, they have radio luminosities of the order of the supernova remnant Cas A (see Table 1). Here 1 shall evaluate the probability of 01 and 02 being supernovae remnants. (The double source 3C 69 is inconsistent in form and size with a supernova remnant.)
