Zheng, SU, on behalf of the Sloan Digital Sky Survey II collaboration, report the discovery of twelve additional 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. A. Aragon-Salamanca, University of Nottingham; M. Bremer, University of Bristol; M. Turatto, University of Padova; A. Goobar, University of Stockholm; J. Sollerman, University of Copenhagen; P. Ruiz-Lapuente and F. Castander, University of Barcelona; A. Romer, University of Sussex; C. Collins, Liverpool John Moores University; and J. Lucey and A. Edge, University of Durham, report that spectroscopy obtained by R. Nichol and M. Smith on Sept. 17 UT with the ESO 3.6-m New Technology Telescope (NTT) shows five of the supernovae (2006fs, 2006fy, 2006fz, 2006fx, 2006fw) to be type-Ia events, one (2006fq) to be a type-IIP event, and two (2006fu and 2006fv) to be possible type-Ia events. Spectroscopic observations with the Subaru 8-m telescope by N. Takanashi, Y. Ihara, T. Morokuma, K. Tokita, K. Konishi, and N. Yasuda on the same night indicates that two of the other supernovae (2006gb and 2006ft) are of type Ia, and a third (2006fr) is a possible type-Ia event. Subaru observations also confirm 2006fx as a type-Ia supernova. The twelfth object, 2006ga, was observed by both NTT and Subaru and appears to be a possible type-I event. The discovery magnitudes tabulated below are all g magnitudes, and discovery dates are UT. Spectroscopic redshifts are given in the column labelled "z". Peak g magnitudes and dates (all 2006) are estimates from early fits to the multi-band light curves. SN Discov. R.A. (2000.0) Decl.
