2009CBET.1980....1Y

H. Yamaoka, Kyushu University; K. Ayani, Bisei Astronomical Observatory (BAO); and S. Honda and K. Kinugasa, Gunma Astronomical Observatory (GAO), report that low-resolution spectra of M31N 2009-10b (cf. CBETs 1967, 1971, 1973) were obtained on Oct. 15.6 UT with the BAO 1.01-m telescope and on Oct. 15.5 with the GAO 1.5-m telecsope. These show an almost-featureless blue continuum with narrow P-Cyg profiles of Balmer lines, which strongly resemble those of the fast nova V1280 Sco at two days before maximum light (Naito and Narusawa, IAUC 8803).
