Zheng, SU, on behalf of the Sloan Digital Sky Survey II collaboration, report the discovery of ten 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 Oct. 24, 26, 27, and 28 UT show that seven of the new objects (2006lj, 2006lk, 2006lq, 2006lp, 2006lm, 2006lr, 2006ll) are type-Ia supernovae. B. Bassett, K. van der Heyden, and P. Vaisanen, South African Astronomical Observatory, report that a spectrum of 2006ln, taken with the South African Large Telescope on Oct. 23, shows it to be a type-Ia supernova. J. Eastman, J. L. Prieto, L. Watson, R. Assef, K. Schlesinger, D. DePoy, OSU; and A. Crotts, Columbia University, report that spectroscopic observations with the Hiltner 2.4-m at MDM Observatory on Oct. 27 indicate that 2006lo is a type-Ia supernova. J. Marriner, D. McGinnis, and G. Miknaitis report that spectroscopic observations with the ARC 3.5-m telescope at APO on Oct. 23 indicated that 2006ls was a probable type-I supernova; a second spectroscopic exposure of this object, at MDM on Oct. 29, indicates that it appears to be a peculiar type-I event. 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.
