SUPERNOVA 2010jl IN UGC 5189A
     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).
