T. G. Hawarden, U.K. Schmidt Telescope Unit, Siding Spring Observatory, reports that an observation on July 14 by D. A. Jauncey with the image-dissector scanner on the 390-cm Anglo-Australian telescope shows that the spectrum of this supernova (cf. IAUC 3091) closely resembled that of 1972E in NGC 5253 some 200-230 days after maximum. Broad H-alpha emission was present, and there were broad emission features with P Cyg profiles centered at 4700, 5300, 5900 and possibly 7100 A. The supernova, of type I, was evidently near maximum at the epoch of the discovery plate. The position is now given as R.A. = 3h38m00s.45, Decl. = -44o10'17" (equinox 1950.0).
