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 Nov. 16 UT indicate that three of them (2006nt, 2006nu, and 2006nv) are type-Ia supernovae, and one (2006ns) is a type-II supernova. M. Stritzinger and J. Sollerman, Dark Cosmology Center (DCC); A. Goobar, University of Stockholm; together with Nichol and Smith, report that observations by Stritzinger, G. Leloudas, and C. Henriksen (DCC) with the Nordic Optical Telescope on Nov. 17 indicate that 2006nw is a normal type-Ia supernova, 2006oa is a type-Ia supernova with a spectrum similar to that of 1991T, 2006ob is a type-Ia supernova with a spectrum similar to that of 1991bg, 2006nx has the spectrum of a type-Ib or type-Ic hypernova event, and 2006ny appears to be a type-IIp event. S. Blondin, M. Modjaz, R. Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 350-740 nm) of 2006nz, obtained on Nov. 17.21 by L. Macri with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-Ia supernova around maximum light; the spectrum appears reddened due to significant contamination from the underlying host galaxy. Cross-correlation with a library of supernova spectra indicates that SN 2006nz is most similar to the type-Ia supernova 2002bo at -2 days from maximum light; adopting a recession velocity of 11360 km/s for the host galaxy (derived from narrow absorption lines in the host galaxy spectrum), the maximum absorption in the Si II line (rest 635.5 nm) is blueshifted by roughly 13000 km/s. 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.
