S. Fujikawa (Kagawa, Japan) reported (to NAOJ) his discovery of possible nova (mag 9.4) using a f.l.=105mm camera lens + CCD. The object also detected in the image taken on Aug. 09.8061 UT. Additional measurements by Fujikawa using PENTAX 100SDUF (F/4, f.l.=400mm) digital camera: Aug. 12.8174, 9.4. S. Nakano measured the last image and get the position end figures of 38s.57, 53".4 (+/- 1".5). There is a faint cataloged star in the neightbourhood of the reported position.
