Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics, report that a spectrogram (range 350-740 nm) of 2006ck (cf. CBET 518), obtained by P. Berlind on May 23.21 UT, shows it to be a supernova of type Ic around maximum light. The spectrum is most similar to that of the type-Ic supernova 1994I (Filippenko et al. 1995, Ap.J. 450, L11) at 2 days past V-band maximum.
