A. Crotts, Columbia University; J. Eastman, D. DePoy, and J. L. Prieto, Ohio State University; and P. Garnavich, University of Notre Dame, report that spectra of the possible bright supernova in UGC 4904 (cf. CBET 666) were obtained with the Hiltner 2.4-m telescope (+ CCDS spectrograph) at MDM Observatory on Oct. 11.5 UT. The reduced spectra show many broad features consistent with a supernova spectrum. Assuming a recesion velocity for the host galaxy of 1670 km/s (Nordgren et al. 1997, A.J. 114, 913), several emission features are found to be consistent with He I 381.9-, 447.1-, 587.5-, and 706.5-nm. The spectrum also shows a very weak absorption feature consistent with H-alpha. This object is likely a type-Ib supernova from the strong He I features present in the spectrum.
