M. Modjaz, R. Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics, report that a spectrogram (range 350-740 nm) of SN 2005U (cf. IAUC 8473), obtained by P. Berlind on Feb. 1.51 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 with heavy host-galaxy light contamination. Adopting the NED recession velocity of 3088 km/s for the host galaxy, the expansion velocity derived from the minimum of the H_beta line is about 10000 km/s.
