Zheng, SU, on behalf of the Sloan Digital Sky Survey II collaboration, report the discovery of eight new supernovae on multiple g, r, and i images taken with the SDSS 2.5-m telescope at APO by the SDSS observing team. Romani, Zheng, Sako, Wheeler, and Schneider, together with U. Hopp (University of Munich) and W. Kollatschny (University of Goettingen), report that spectroscopic observations with the Hobby Eberly Telescope on Dec. 13, 15, and 18 UT indicate that seven of the new objects are type-Ia supernovae and that the eighth, 2006sz, is a probable type-Ia supernova. The discovery magnitudes tabulated below are all SDSS g magnitudes. Spectroscopic redshifts are given in the column labelled "z". Peak dates (all 2006) are approximate estimates from early fits to the multi-band light curves or from the spectra. SN Discov. R.A. (2000.0) Decl.
