K. Kinugasa, Gunma Astronomical Observatory (GAO), writes that K. Nishiyama (Kurume, Fukuoka, Japan) and F. Kabashima (Miyaki-cho, Saga, Japan) reported a brightening of a USNO-B1.0-catalogue star located at R.A. = 17h44m08s.478, Decl. = -26o05'47".37 (equinox 2000.0) – from fainter than mag 13.5 on their unfiltered CCD patrol image (105-mm-f.l. camera lens) taken on Apr. 18.705 UT to mag 12.5 on Apr. 21.681 (with additional magnitudes as follows: Apr. 21.711, 11.7; 22.720, 11.7; 23.760, 12.3; 25.683, 12.2; 27.815, 12.4). Kinugasa, S. Honda, and O. Hashimoto took low-dispersion (range 400-800 nm, resolution about 500) and high-dispersion (range 480-664 nm, resolution about 40000) spectra of this object on Apr. 27.7 with the GAO 1.5-m telescope (+ GLOWS and GAOES, respectively), which show a broad (FWHM about 2600 km/s) and double-peaked H_alpha emission, with several emission lines of Fe II and O I – indicating that this object is a classical nova in decline phase. The astrometry (using the USNO-A2.0 reference stars) with images also taken on Apr. 28.8 (when the nova was at V = 13.7, R = 12.9, I = 10.6) with the 1.5-m telescope (+ GLOWS), reveals position end figures 08s.44, 48".7 – which is about 1".4 from the USNO-B1.0 star, so the nova may be unrelated to it. H. Yamaoka, Kyushu University, adds that the ASAS-3 system (Pojmanski 2002, Acta Astr. 52, 397) also detects the object at the following V magnitudes: Apr. 16.374, [14.0:; 19.304, 12.4; 22.332, 13.4; 25.285, 13.6; 30.293, [14.0:.
