Zheng, SU, on behalf of the Sloan Digital Sky Survey II collaboration, report the discovery of five 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. Marriner, D. McGinnis, G. Miknaitis, G. Saurage, W. Ketzeback, J. Dembicky, and R. McMillan report that spectroscopic observations with the ARC 3.5-m telescope at APO on Oct. 27, 29, and 31 UT indicate that two of the events are type-Ia supernovae (2006mt and 2006mv) and the other three (2006mu, 2006mw, 2006mx) are probable 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.
