M. Yamanaka and T. Okushima, Hiroshima University; A. Arai, Kyoto Sangyo University; and M. Sasada and H. Sato, Hiroshima University, report that they obtained low-resolution optical spectra of 2010jl (cf. CBETs 2532, 2536) on Nov. 5.8 UT at the Higashi-Hiroshima Observatory, Hiroshima University (R = 400), and at the Koyama Astronomical Observatory, Kyoto Sangyo University (R = 500). The spectra show emission lines of H-beta and H-alpha at 470-490 and 640-670 nm. These features have multiple emission lines with more-narrow and broader components. The FWHM velocities of the more-narrow components were measured to be roughly below 500, while the FWHM of the broader components are 18000 km/s. The spectra also exhibit weak emission lines of He I at 590 and 710 nm. These profiles are similar to those of the luminous type-IIn supernova 2006tf at a month after maximum light (Smith et al. 2008, Ap.J. 686, 467).
