As first announced on CBET 2261, K. Nishiyama (Kurume, Japan) and F. Kabashima (Miyaki, Japan) report their discovery of a possible Milky Way nova (mag 11.2) on two unfiltered CCD frames (limiting mag 13.2) taken around Apr. 23.782 UT using a 105-mm f/4 camera lens (+ SBIG STL6303E camera). They used five deeper unfiltered CCD frames taken around Apr. 23.791 with a Meade 0.40-m reflector to measure the following precise position for the variable: R.A. = 17h53m02s.99 ± 0s.01, Decl. = -28o12'19".4 ± 0".1 (equinox 2000.0). A USNO-B1.0-catalogue star of red mag 17.4 has position end figures 03s.11, 19".0. Additional magnitudes for the variable (via unfiltered CCD, and from Nishiyama and Kabashima, unless noted otherwise): 1996 Sept. 12, [17.5 (Digitized Sky Survey, red plate); 2010 Apr. 2.831, [12.9; 16.749, [13.1; 20.262, [11.0 (W. Liller, Vina del Mar, Chile; Kodak TP film, orange filter, 85-mm camera lens); 24.660, 11.1 (T. Yusa, Osaki, Japan, 0.30-m reflector; position end figures 02s.98, 19".3); 24.673, 11.6; 24.752, I_c = 10.21 (H. Maehara, Kwasan Observatory, Kyoto University, 25-cm telescope + CCD); 24.754, R_c = 12.47 (Maehara); 24.755, V = 15.33 (Maehara). Further observations appear on CBET 2264.
