Abstract (from CDS):
S. Nakano, Sumoto, Japan, reports the discovery of a possible nova (mag 9.5) by Hiroshi Abe (Yatsuka-cho, Matsue, Shimane-ken, Japan) on several 30-s survey frames (limiting mag about 11.5) taken around Aug. 8.54 UT using a Canon EOS Kiss Digital Camera (+ 35-mm f/2.8 Pentax lens), the new object measured by Nakano from Abe's JPEG image to be at R.A. = 19h54m24s.3, Decl. = +20o52'47" (equinox 2000.0; estimated uncertainty ± 8"); Abe notes that nothing was visible at this location on frames taken on July 23, 31, and Aug. 4. Nakano forwards the following position end figures for the new object from K. Kadota (Ageo, Saitama-ken, Japan, 0.25-m reflector + unfiltered CCD, Aug. 8.682, mag 9.4): 24s.64, 51".9; Kadota adds that a star of red mag 18.1 and blue mag 17.6 in the USNO-A2.0 catalogue has position end figures 24s.66, 51".7. Visual magnitude estimates forwarded by E. Waagen, AAVSO: Aug. 9.006, 9.3 (S. Swierczynski, Dobczyce, Poland); 9.093, 8.7 (M. Komorous, London, ON, Canada); 9.188, 8.4 (R.
