The Nearby Supernova Factory reports that a spectrum (range 340-1000 nm) of SN 2005bt (IAUC #8518), obtained April 24.5 UT with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope, shows it to be a Type II with well developed hydrogen features as well as He I 587.6 nm. Assuming the NED velocity for the host, H-alpha has an expansion velocity of 6800 km/s.
