Possible Nova in M31 : spectroscopic confirmation

33.png

We carried out the low-resolution spectroscopic observations of "Possible Nova in M31" on Jan. 11 according to the discovery by K. Nishiyama and F. Kabashima. Our observations were performed by 1.3m Araki telescope and LOSA/F2 spectrograph. The spectrum shows clearly P-Cygni profiles at H-alpha, H-beta, Fe II and O I lines. The absorption minmum at the H-alpha line is blue-shifted by about 1300km/s. These features indicate that the object is a classical nova in very early phase.
