We performed optical spectroscopic observations of PNV J00424483+4118007 using 1.3m Araki telescope with our low-dispersion optical spectrograph (LOSA/F2: R~580@6000) on July 29 and 30 UT at Koyama Astronomical Observatory, Kyoto Sangyo University, Japan.
The figure shows our preliminary specum on July 30. We detected a broad H-alpha emission line with FWHM = 1800 (+/- 200) km/s in our preliminary spectra on both nights. In spectra on July 30, H-beta and Fe II multiplet emissons were seen. Although this object is very faint (CCD~17), our spectrum shows a conitmuum light accompanied with a blue-trend. This means that the interstellar reddening toward to the object would be small. These results suggest that PNV J00424483+4118007 is a 'Fe II'-type classical nova in M31.
