M. Modjaz, R. Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 350-740 nm) of SN 2005J (cf. IAUC 8467), obtained by M. Calkins on Jan. 19.40 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-II supernova, probably within a few weeks past explosion. The spectrum consists of a blue continuum and Balmer-line P-Cyg features. Adopting the NED recession velocity of 4182 km/s for the host galaxy, the expansion velocity derived from the minimum of the H_beta line is about 10000 km/s. A noisy spectrogram of SN 2005K (IAUC 8468) taken by Calkins on Jan. 19.42 reveals it to be a type-II supernova. The spectrum shows P-Cyg features of H_alpha and H_beta, and the expansion velocity derived from the minimum of the H_beta line is about 5000 km/s (adopting the NED recession velocity of 8151 km/s for the host galaxy).
