2009CBET.2058....3H

K. Hornoch, Astronomical Institute, Ondrejov, Czech Republic; and O. Pejcha, Department of Astronomy, Ohio State University, report low-resolution optical spectroscopy (range 380-720 nm, resolution 0.7 nm) and optical photometry of M31N 2009-11d. Spectra were obtained using the Boller & Chivens CCD Spectrograph on the 2.4-m Hiltner telescope at MDM Observatory. Magnitude measurements were obtained from images taken with RETROCAM on the 2.4-m Hiltner telescope and with the 0.65-m telescope (+ G2CCD-3200) at Ondrejov. The spectrum of M31N 2009-11d obtained by Pejcha on Nov. 21.31 UT (only 2.1 days after its first optical detection made by Pietsch et al.) shows Balmer lines with P-Cyg profiles. One day later, on Nov. 22.21, the Balmer lines showed only an emission component, and Fe II emission lines emerged, confirming this object as a "Fe II"-class nova near maximum light. The HWZI of H-alpha was about 2500 km/s. Magnitudes for 2009-11d: Nov. 21.285, r' = 16.43 ± 0.08 (Pejcha and Hornoch, 2.4-m telescope + Sloan r' filter); 21.287, g' = 16.53 ± 0.10 (Pejcha and Hornoch, 2.4-m telescope + Sloan g' filter); 21.799, R = 17.26 ± 0.10 (Hornoch and P. Kusnirak, 0.65-m Ondrejov telescope); 23.060, R = 17.3 ± 0.2 (Hornoch). Hornoch also reports position end figures 16s.88, 53".6 for M31N 2009-11d.
