As first announced on CBET 3040, John Seach (Chatsworth Island, NSW, Australia) reported his discovery of a possible new nova (mag 10.2) on three CCD images (limiting mag 11.0) taken on Feb. 26.543 UT with an SLR camera with a 50-mm f/1.0 lens; he gave the position of the variable as alpha = 10h50m20s, Decl. = -64o06'48" (equinox 2000.0); nothing is present at this position on his image from Feb. 23.424 (limiting mag 11) or on a red Palomar Sky Survey image. Selected visual magnitudes for the variable: Mar. 4.024, 10.5 (S. Bais, Olavarria, Argentina; via E. Waagen, AAVSO); 4.986, 10.5 (J. G. de S. Aguiar, Campinas, Brazil); 7.117, 10.9 (Bais); 7.990, 11.0 (Aguiar); 9.990, 11.0 (Aguiar); 11.003, 11.4 (Bais); 11.995, 11.2 (Aguiar); 13.075, 12.5 (Bais); 15.049, 12.3 (Bais). Additional non- visual magnitudes for the variable: Feb. 25.733, 11: (possible detection at limit by Seach); 27.441, 10.4 (Seach); Mar. 1.155, V = 10.55 (A. Oksanen and C. Harlingten, using a 0.50-m telescope at San Pedro de Atacama, Chile; position end figures 19s.66, 46".7); 5.323, V = 10.87 (Oksanen); 5.325, B = 11.54 (Oksanen); 7.295, R = 10.27 (Oksanen); 7.296, V = 11.21, B = 11.88 (Oksanen); 10.375, V = 11.54 (Oksanen); 10.376, B = 12.21 (Oksanen). Additional V magnitudes sent by Waagen: Mar. 6.352, 11.02 (J. Hambsch, Mol, Belgium): 7.528, 11.27 (T. Bohlsen, Armidale, NSW, Australia): 8.361, 11.32 (Hambsch); 10.468, 11.52 (Bohlsen); 11.472, 11.77 (Bohlsen); 12.550, 11.99 (T. G. Tan, Dalkeith, W. Australia): 13.474, 12.11 (Tan); 14.278, 12.17 (Hambsch). Oksanen notes that a nearby very faint star is visible near the plate limit (mag perhaps 19) on a red U.K. Schmidt telescope IIIa-F plate (RG610 filter) taken on 1994 Apr. 9, but he adds that the star is not exactly at the position of the presumed nova. The variable was designated TCP J10502000-6406480 when it was posted at the Central Bureau's TOCP webpage, and it has been assigned the GCVS designation V834 Car by N. N. Samus.
