Further to CBET 268, J. Frieman provides the following information for three additional apparent supernovae found by the Sloan Digital Sky Survey II collaboration on multiple g, r, and i images taken with the SDSS 2.5-m telescope. Spectroscopy has not yet been obtained, but their multi-epoch light curves are suggestive of type-Ia supernovae (see Poznanski et al., 2002, PASP 114, 833; Howell et al. 2005, Ap.J., in press, and http://xxx.lanl.gov/abs/astro-ph/?0509195), with characteristic post-peak plateaus in i-band brightness.
