A. Gal-Yam, D. J. Sand, S. B. Cenko, D. C. Leonard, and J. Muller report on behalf of the CCCP that a preliminarily reduced spectrum (range 4000 - 9500 A) of SN 2005bx (Rich et al., CBET # 148) obtained using the double spectrograph mounted on the Palomar Observatory 200" Hale telescope, on Apr. 30, 2005, UT, shows this is a type IIn SN, similar to SN 1988Z (e.g., Filippenko 1997). This confirms an earlier report by the Nearby Supernova Factory (ATEL #474). Narrow Balmer emission lines with broad bases are superposed on a blue continuum.
