6121 2020-02-14 13:13:47 Miho Kawabata Miho Kawabata None Other 0 1 The spectrum shows the strong emission lines of H-alpha and H-beta with the blue continuum. The FWHM of the H-alpha is measured to be around 1000km/s. The emission line peaks of H-alpha and H-beta are blueshifted to 400-500km/s, which is consistent with the helioncetric velocity of M31 within error. These features are possibly similar to that of the luminous blue variable, while the spectrum cannot be distinguished from the luminous red nova. 2020TNSCR.499....1K
