Zheng, SU, on behalf of the Sloan Digital Sky Survey II collaboration, report the discovery of seven 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. For one of the candidates, 2006fc, a second epoch of imaging confirming the apparent supernova was taken on Sept. 12 UT by A. Rau, E. Ofek, A. Soderberg, and S. Kulkarni using the Palomar 1.5-m telescope. 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 the night of Sept. 13 UT with the ESO 3.6-m New Technology Telescope show five of the new supernovae to be type-Ia events, one to be a type II event (2006ez), and one to be a possible type-Ia event (2006fa). 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.
