Possible Nova in Puppis
Abstract
T. Kato, Kyoto University, reports the discovery by Kazuyoshi Kanatsu (Matsue, Shimane, Japan) on his T-Max 400 film exposures of a new variable star at R.A. = 7h37m58s, Decl. = -25o56'51" (equinox 2000.0). Kanatsu finds no apparent counterpart on the Digital Sky Survey. K. Takamizawa (Saku-machi, Nagano) reports that the new object was not present on 22 T-Max 400 exposures (limiting mag 14) taken by himself between between 1994 Mar. 14 and 1999 Dec. 3; he notes the presence of a close stellar companion of mag 14.5, which is apparently a red star (red mag 13.6) in the USNO A2.0 catalogue having position end figures 58s.43, 46".8. Available magnitudes: 2000 Jan. 15.72 UT, [11.7 (Kanatsu; T-Max 400); Nov. 28.703, 8.6 (Takamizawa; T-Max 400); Dec. 22.578, 8.8 (Takamizawa); 22.731, 8.7 (Kanatsu); 30.585, 8.8 (A. Takao, Kitakyushu, Fukuoka, Japan; unfiltered CCD); 30.612, 9.2 (R. Stubbings, Drouin, Victoria, Australia; visual).
