S. Nakano, Sumoto, Japan, reports the discovery by Akihiko Tago (Tsuyama, Okayama-ken) of a possible nova (mag 7.4) on three 30-s CCD exposures taken around Mar. 15.787 UT with a Canon 20Da digital camera (+ 70-mm f/3.2 lens; limiting magnitude 13.2 ± 0.2), with Tago giving the position of the variable as R.A. = 20h28m15s, Decl. = +41o49'.0 (equinox 2000.0), and noting that nothing was visible at this position on his frame taken on Mar. 12.796 (limiting mag 12). Tago adds that an image taken by himself on Mar. 16.75 shows the variable at mag 7.5. Nakano provides his own measure of the position end figures (estimated uncertainty perhaps ± 5" or more) from Tago's discovery image: 13s.22, 48'45".5, magnitude 6.8 ± 0.4. Nakano further adds that K. Nishiyama and T. Sakamoto, Bisei Spaceguard Center, have confirmed the variable star at mag 6.7 on an unfiltered CCD image taken with the 1.0-m f/3.0 reflector on Mar. 16.768, giving the object's position end figures as 12s.52, 48'36".5. A red USNO-catalogued star is located at position end figures 12s.505, 48'36".69 (red mag 18.5).
