After the Central Bureau received the above report, S. Nakano, Sumoto, Japan, forwarded two independent discoveries of this possible nova to the Bureau, the first by Hideo Nishimura (Miyawaki, Kakegawa, Shizuoka-ken, Japan) on two 13-s CCD exposures (limiting mag 10.5) taken on Apr. 25.763 UT with a Minolta 120-mm f/3.5 camera lens (+ Canon EOS 5D digital camera mounted on a Takahashi EM100 equatorial telescope), with Nishimura providing magnitude 8.3 and position end figures 12s.96, 48".1. The second report forwarded by Nakano is from Tadashi Kojima (Tsumagoi, Agatsuma-gun, Gunma- ken, Japan), who found the presumed nova on two CCD frames (limiting mag 11.2) taken on Apr. 25.738 UT using a Canon EOS 40D digital camera with a 50-mm f/2.8 camera lens, mounted on a Sky-Memo equatorial instrument; Nakano measured mag 8.8 and position end figures 13s.46, 44".7 (uncertainty ± 5") from Kojima's frame.
