Zheng, SU, on behalf of the Sloan Digital Sky Survey II collaboration, report the discovery of an apparent supernova (magnitude g = 20.4) on g, r, and i images taken with the SDSS 2.5-m telescope at APO by the SDSS observing team on Oct. 3 UT. Confirming SDSS g, r, and i images were obtained with the Hiltner 2.4-m telescope at MDM on Oct. 8. The new object is located at R.A. = 23h21m19s.48, Decl. = +0o15'35".1 (equinox 2000.0). The nearby apparent-host galaxy's center is located at position end figures 19s.19, 32".8; this galaxy has a prior SDSS spectrum indicating a redshift of 0.03. SN 2006iw was not detected in an image taken on Oct. 1, with a 5-sigma upper g-magnitude limit of approximately 22.6.
