H. McNaught, Anglo-Australian Observatory, reports his discovery of an apparent supernova of mag 18.5 on an R plate taken by M. Hartley with the U.K. Schmidt Telescope (UKST) on Aug. 15. The supernova is at R.A. = 0h15m20s.62, Decl. = -24o53'50".5 (equinox 2000.0) and is located in a spiral arm, 1".0 east and 16".4 south of the galaxy's centre. The new object was confirmed on a CCD image taken by McNaught and G. J. Garradd with the 1.0-m telescope at Siding Spring on Aug. 16. No image appeared at this location on various UKST plates taken > 5 years ago. A nearby star of mag 17.5 has position end figures 21s.70, 42".2. IAUC 6056 SUPERNOVA 1994Y IN NGC 5371 William Wren, McDonald Observatory, reports his visual discovery of an apparent supernova in NGC 5371 (R.A. = 13h55m.7, Decl. = +40o28', equinox 2000.0), located about 28" west and 14" north of the galaxy's nucleus. Wren provides the following magnitude estimates as seen through a 0.9-m telescope: July 31.18 UT, [16.5; Aug. 19.15, 15.0. Y. Paik, A. V. Filippenko, R. R. Treffers, and S. D. Van Dyk, University of California at Berkeley; and M. W. Richmond, Princeton University, report that R-band images of NGC 5371 were obtained in August as part of the Leuschner Observatory Supernova Search. On Aug. 12, SN 1994Y is 2.7 mag fainter than the comparison star 61" west and 5" south of it, barely below the threshold for automatic detection. On Aug. 16, it is perhaps 2 mag fainter than the comparison star, but the image quality is very poor. Images obtained on Aug.3,6, and 9 show little or nothing due to clouds. SN 1994Y is measured as 34" west and 11" north of the galaxy's nucleus. IAUC 6058 Guy M Hurst
