Abstract (from CDS):

As first announced on CBET 2262, K. Nishiyama (Kurume, Japan) and F. Kabashima (Miyaki, Japan) report their discovery of another possible Milky Way nova (mag 8.6) on two unfiltered CCD frames (limiting mag 13.1) taken around Apr. 25.788 UT using a 105-mm f/4 camera lens. Follow-up unfiltered CCD frames (limiting mag 17.3) taken around Apr. 25.796 using a 0.40-m reflector yield the following precise position for the variable: R.A. = 16h55m13s.16, Decl. = -38o03'46".9 (equinox 2000.0). Additional magnitudes (obtained via unfiltered CCD unless otherwise noted) for the new variable: 1995 June 4, [18.0 (Digitized Sky Survey, red plate; via Nishiyama and Kabashima); 2010 Apr. 23.786, [12.9 (Nishiyama and Kabashima); 24.74, [10.2: (Y. Sakurai, Mito, Ibaraki-ken, Japan); 24.757, [13.2 (Nishiyama and Kabashima); 25.734, 8.8 (Sakurai; measured by S. Nakano, Sumoto, Japan; independent discovery); 25.738, 8.8 (T. Kojima, Tsumagoi, Agatsuma-gun, Gunma-ken, Japan; measured by Nakano; independent discovery); 25.763, 8.3 (H. Nishimura, Miyawaki, Kakegawa, Shizuoka-ken, Japan, via Nakano; independent discovery); 26.307, V = 8.55 (S. Kiyota, Tsukuba, Japan, 30-cm reflector; position end figures 13s.22, 46".8); 26.308, R_c = 7.75 (Kiyota); 26.309, I_c = 6.92 (Kiyota); 26.310, B = 10.18 (Kiyota); 26.4, about 8.2 (E. Guido and G. Sostero; 0.25-m reflector; position end figures 13s.17, 47".8); 27.21, 10.3 (H. Koberger and W. Vollmann, 0.6-m reflector at Tenerife; position end figures 13s.16, 46".9); 29.680, I_c = 8.77 (H. Maehara, Kwasan Observatory); 29.681, R_c = 9.45 (Maehara); 29.683, V = 11.21 (Maehara); 29.685, B = 12.03 (Maehara). Visual magnitude estimates: Apr. 27.154 UT, 11.0 (A. Amorim, Florianopolis, Brazil); May 2.010, 11.9 (Amorim); 4.424, 12.9 (M. Linnolt, Ocean View, HI, U.S.A., via the AAVSO). Maehara's spectrogram from Apr. 29.704 UT (25-cm telescope) shows H_alpha and H_beta emission lines with a FWMH of 4000 km/s. Additional details appear also on CBET 2265. E. Kazarovets, Russian Academy of Sciences, writes that the GCVS designation V1311 Sco has been assigned to this nova.
