As first reported on CBETs 2128 and 2139 (where additional details may be found), S. Nakano, Sumoto, Japan, forwarded the discovery by H. Nishimura (Miyawaki, Kakegawa, Shizuoka-ken, Japan) of an apparent nova (mag 8.4) on frames taken on Jan. 15.857 UT with a Canon EOS 5D camera (+ Minolta 120-mm f/3.5 lens); Nakano measured mag 8.8 and the following position from the discovery image: R.A. = 17h39m40s.90, Decl. = -21o39'50".5 (equinox 2000.0). Additional CCD magnitudes: 2009 Nov. 3, [11.0 (Nishimura); 2010 Jan. 13.86, [9.5: (Nishimura); 14.865, 10.1 (Nishimura; measured by Nakano; limiting mag 10.6); 16.856, 8.4 (K. Itagaki, Takanezawa station, Tochigi-ken, Japan, 0.30-m reflector; position end figures 40s.94, 47".9); 16.860, 8.2 (K. Kadota, Ageo, Saitama-ken, Japan, 0.25-m reflector; position end figures 40s.97, 47".4); 18.299, 8.4 (W. Vollmann, Vienna, Austria, and H. Koberger, Vilaflor, Tenerife; green-band); 22.250, 9.5 (Vollmann and Koberger). Kadota adds that nothing is visible at this position on a red Digitized Sky Survey image from 1997 (limiting mag estimated to be 20 by Nakano). H. Maehara, Kwasan Observatory, Kyoto University, reports that a low- resolution spectrum (range 400-800 nm), obtained on Jan. 22.890 with a 25-cm telescope at Kwasan Observatory, shows H_alpha and Fe II emission lines and suggests that this object is a classical nova just after maximum. E. Kazarovets and N. Samus report that the GCVS designation V2673 Oph has been assigned to this nova.
