SUPERNOVA 2005ci IN NGC 5682
     M. Modjaz, R. Kirshner, and P. Challis, Harvard-Smithsonian Center
for Astrophysics, report that a spectrogram (range 340-740 nm) of SN
2005ci (cf. IAUC 8541), obtained by M. Calkins on June 12.34 UT with the
F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a
type-II supernova.  The spectrum consists of a flat continuum and P-Cyg
lines of H_alpha and H_beta.  Adopting the NED recession velocity of 2291
km/s for the host galaxy (from Falco et al. 1999, PASP 111, 438), the
expansion velocity derived from the minimum of the H_beta line is about
13000 km/s.
