Abstract (from CDS):

S. Nakano, Sumoto, Japan, reports the discovery by Hiroshi Kaneda (Sapporo, Japan) of an apparent nova (mag 8.7) on three 4-s unfiltered CCD frames taken on 2007 Dec. 25.35 UT using a Nikon D40 digital camera (+ 105-mm f/2.5 lens), with an apparent independent discovery made by A. Tago at mag 8.3 on his two patrol frames taken on Dec. 26.38 using a Canon 20D digital camera (+ Pentax 105-mm f/3.2 lens). Nakano's measurement of the variable from Tago's image yielded the position R.A. = 19h48m08s.81, Decl. = +21o15'29".9 (equinox 2000.0) and mag 7.8. Additional CCD magnitudes: Dec. 8, [10-11 (Kaneda); 26.342, 7.1 (K. Itagaki, Yamagata, Japan, 0.60-m f/5.7 reflector; position end figures 08s.84, 27".6); 26.355, 7.7 (Kaneda; position end figures 08s.89, 26".8). Kaneda and K. Kadota (Ageo, Japan) note that a USNO-B1.0- catalogue star has position end figures 08s.871, 26".81 and mag about 20. Spectroscopy by numerous observers, as reported by H. Yamaoka and U. Munari on CBETs 1181 and 1183, confirm the object as a nova. Visual magnitude estimates for V459 Vul by A. Pereira, Cabo da Roca, Portugal: Dec. 26.79, 8.0; 27.79, 7.7; 30.80, 7.9.
