Nakano, Sumoto, Japan, reports the discovery of a possible nova by Kesao Takamizawa, Saku-machi, Nagano-ken, on two T-Max 400 films taken Feb. 7.839 and 7.842 UT using a 10-cm f/4.0 lens. Y. Kushida, Yatsugatake South Base Observatory, provides the following position: R.A. = 19h05m26s.57, Decl. = -1o42'03".5. Takamizawa notes that there is no image brighter than mag 12-14 at this position on films taken on 1994 May 12, June 14, and Oct. 23; there is a nearby star of mag 12.1. Available magnitude estimates, the last two being visual estimates supplied by E. Waagen, AAVSO: Feb. 7.839, 8.1 (Takamizawa); 8.854, 8.4 (Takamizawa); 8.873, 7.5: (Kushida); 9.435, 8.2 (C. Scovil, Stamford, CT); 9.531, 8.5 (P. Collins, Scottsdale, AZ). Collins notes that the star has a reddish color. SUPERNOVA 1995C IN ANONYMOUS GALAXY Robert H. McNaught, Anglo-Australian Observatory, reports his discovery of an apparent supernova (mag about 17.5) on a U.K. Schmidt Telescope (UKST) R plate taken by K. S. Russell on Feb. 8.74 UT. SN 1995C is located at R.A. = 12h04m02s.52, Decl. = -31o36'02".3 (equinox 2000.0, uncertainty 0".2 in R.A. and 0".4 in Decl.), which is 14".7 east and 8".5 south of the galaxy's center. The object does not appear on an ESO R survey plate or on a UKST R plate taken on 1993 May 23. Confirmation was made via an unfiltered CCD image taken Feb. 9.56 by McNaught and D. J. Asher with the 1.0- m telescope at Siding Spring Observatory. A nearby star of mag R about 18 has position end figures 03s.07, 26".0. COMET 19P/BORRELLY Total visual magnitude estimates: Jan. 27.89 UT, 9.7 (G. A. Milani, Cima Ekar, Italy, 20x80 binoculars); 30.24, 10.1 (C. S. Morris, Whitaker Peak, CA, 0.26-m reflector); Feb. 3.15, 10.4 (A. Hale, near Chaparral, NM, 0.2-m reflector); 8.10, 10.7 (C. E. Spratt, Victoria, BC, 0.20-m reflector). COMET C/1994 T1 (MACHHOLZ) Total visual magnitude estimates by Morris at Whitaker Peak: Jan. 2.21 UT, 11.8; Feb. 1.18, 13.3. 1995 February 9 (6133) Daniel W. E. Green
