Snedden, APO; N. Takanashi and K. Tokita, UoT; K. van der Heyden, SAAO; S. Watters, APO; C. Wheeler, University of Texas; N. Yasuda, UoT; and C. Zheng, SU, on behalf of the Sloan Digital Sky Survey II collaboration, report the discovery of eleven new type-Ia 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 Nov. 11, 14, and 15 UT indicate that they are all type-Ia events. 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.
