The image was secured with a CDK17 (17-inch f/6.8 telescope) and SBIG STX. The exposure was 480 seconds with an L filter. The object was estimated at magnitude 14 and the suspect 0.40s W and 9.4"S of the nuclear region. The editor consulted Tom Boles who imaged this galaxy on August 6 but the suspected object was absent. A further image from Ron Arbour on August 12.935UT DID show it at magnitude 17.1 (0.35-m f/6 C14 with end figures 18.41s, 51.7". An independent discovery was also reported to the Central Bureau by F. Ciabattari, E. Mazzoni, and G. Petroni confirming the magnitude 17.2 object on CCD images (limiting mag 19.5) obtained on Aug. 11.94 and 12.83 with a 0.5-m Newtonian telescope (+ FLI Proline 4710 camera) at Borgo a Mozzano, Italy, in the course of the Italian Supernovae Search Project. The new object is located at RA 18h 53m 18s.45, DEC +33 03' 52.7" (2000), 5"W and 8"S. L. Tomasella, A. Pastorello, S. Benetti, E. Cappellaro, P. Ochner, and M. Turatto, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that an optical spectrogram on Aug. 12.98 UT with the Asiago 1.82-m Copernico Telescope shows a blue featureless continuum, consistent with a young type-II supernova. (CBET 3627) Editor: If anyone has imaged this galaxy directly or accidentally in the field of Messier 57 during August please send a report to the editor. Guy M Hurst
