Yamaoka, Kyushu University, writes that several Japanese observers took low-resolution spectra around Apr. 5.8 UT of the possible nova reported on IAUC 8697, including K. Kinugasa (Gunma Astronomical Observatory, 1.5-m telescope; range 400-800 nm, resolution about 500); H. Naito and S. Ozaki (Nishi-Harima Astronomical Observatory, 2.0-m NAYUTA telescope; range 420-790 nm, resolution about 1200); and M. Fujii (Ibara, Okayama, Japan; range 390-860 nm). The spectrum shows a rather flat continuum, on which an H_alpha line shows a clear P-Cyg profile (FWHM of the emission is 500 km/s; the absorption minimum is 700 km/s bluer than the emission peak). Other lines, including H_beta and H_gamma, are seen in absorption. This suggests that the object is a classical nova caught at or slightly before its maximum light. Na I D absorption line (EW = 0.3 nm) indicates that some interstellar reddening exists. N. N. Samus, Russian Academy of Sciences, informs us that this nova has been assigned the designation V2362 Cyg. Further to IAUC 8697, H. Nishimura provides an additional photographic magnitude of V2362 Cyg: Apr. 5.79 UT, 7.9. Visual magnitude estimates: Apr. 5.427, 8.5: (J. D. West, Mulvane, KS); 5.97, 8.5 (M. Reszelski, Szamotuly-Galowo, Poland). SUPERNOVAE 2006bk AND 2006bl Two additional apparent supernovae have been reported from unfiltered CCD images by T. Boles (cf. IAUC 8684): SN 2006 UT R.A.
