USNO-A2.0 0600-28292745 , the SIMBAD biblio

S. Nakano, Sumoto, Japan, reports the discovery by Hideo Nishimura (Miyawaki, Kakegawa, Shizuoka-ken) of a possible nova (mag 10.2) on two Kodak T-Max 400 films (limiting mag 12) taken on Mar. 19.812 UT using a Pentax 6x7 camera (+ 200-mm f/4 lens), the new object's position given as R.A. = 17h42m49s, Decl. = -23o40'07" (equinox 2000.0). Nothing was visible at this location on a film taken by Nishimura on Mar. 17.82 and earlier survey films since 2005 (limiting mag 11.5-12). Nakano adds that K. Kadota (Ageo, Japan) confirms the new star at mag 9.8 on an unfiltered CCD exposure taken on Mar. 20.756 with a 0.25-m f/5 reflector, at position end figures 44s.00, 35".1; Kadota adds that there is no USNO-A2.0 star within 0'.1 of this position (the closest star having position end figures 43s.41, 34".9 and blue mag 18.5, red mag 16.8). Also, K. Itagaki has confirmed the new star using 0.30-m f/7.8 reflector at his Takanezawa station, his CCD image on Mar. 20.806 yielding mag 9.7 and position end figures 43s.99, 35".0. H. Yamaoka, Kyushu University, reports the apparently independent discovery of this apparent nova by Yuji Nakamura (Kameyama, Mie, Japan) at mag 10.0 on unfiltered digital-camera images taken on Mar. 20.812 UT. The variable's position end figures were given by Nakamura as 44s.5, 16" (uncertainty ± 20"); nothing was detected at this position on an image taken by Nakamura on Mar. 17.825 (limiting mag about 13.0). Yamaoka notes that a star of mag 12-13 is located 1' northeast of the new object. Nakano further writes that, following announcement of this nova on CBET 900, he received word of an apparently independent discovery at mag 10.2 by A. Tago (Tsuyama, Okayama-ken, Canon 20Da digital camera + 70-mm f/3.2 lens) on three frames taken around Mar. 20.8; Tago's images from Mar. 18.82 show nothing at the nova's position to mag 11.3.
