Zheng, SU, on behalf of the Sloan Digital Sky Survey II collaboration, report the discovery of six new supernovae on multiple g, r, and i images taken with the SDSS 2.5-m telescope at APO by the SDSS observing team. J. Eastman, J. L. Prieto, L. Watson, R. Assef, K. Schlesinger, and D. DePoy, OSU; and A. Crotts, Columbia University, report that spectroscopic observations with the Hiltner 2.4-m at MDM Observatory on Nov. 8 and 10 UT indicate that 2006nb, 2006nc, and 2006nd are type-Ia supernovae and that 2006ne appears to be a young, highly reddened type-Ia event. 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. 30 and Nov. 10 indicate that 2006mz and 2006na are type-Ia supernovae. 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.
