M. Yamanaka and T. Ui, Hiroshima University; and A. Arai, Kyoto Sangyo University, report that they obtained low-resolution optical spectra of PSN J13085839-1531041 = SN 2011iy on Dec. 14.81 UT at the Higashi-Hiroshima Observatory (resolution R = 400) of Hiroshima University, and at the Koyama Astronomical Observatory (R = 600) of Kyoto Sangyo University. The spectra show the absorption line of Si II at 610 nm, Na I D at 580 nm, and the Ca II infrared triplet at 820 nm – whose lines velocities reach 11000, 10000, and 14000 km/s, respectively. These profiles are similar to those of the type-Ia supernova 2006X at 12 days after B-band maximum (Yamanaka et al. 2009, PASJ 61, 713).
