South African Astronomical Observatory, on behalf of the Sloan
Digital Sky Survey II collaboration, report the discovery of five
supernovae on multiple g', r', and i' images taken on Sept. 9 with
the SDSS 2.5-m telescope at Apache Point Observatory by the SDSS
observing team.  Spectroscopy was obtained with the ARC 3.5-m
telescope (+ DIS) by the 3.5-m observing team, showing four to be
of type Ia and the fifth (2005ei) a likely type-Ia supernova.
The discovery magnitudes tabulated below are all g' magnitudes
except for SN 2005eh (which is an r' magnitude).  The peak
magnitudes are estimated with predicted dates given, and redshifts
are also listed in the final column below.
