Zheng, SU, on behalf of the Sloan Digital Sky Survey II collaboration, report the discovery of four new type-Ia supernovae on multiple g, r, and i images taken with the SDSS 2.5-m telescope at Apache Point Observatory 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 Sept. 20 and 21 UT show that the four new objects are all 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) of expected maximum brightness are estimates from early fits to the multi-band light curves. ---------------------------------------------------------------------------— SN Discov.
