Perley (UC Berkeley) report on behalf of a larger\ncollaboration:\n\nWe have imaged the field of GRB090323 (Ohno et al., GCN 9021) with the\nautomated Palomar 60-inch telescope.  Observations were taken in the Sloan\nr' and i' filters beginning at 2009 Mar 24 04:20 UT (~ 28.30 hr after the\nburst).  Inside the XRT error circle (Kennea et al., GCN 9024) we find a\nsingle source consistent with the position repored by Updike et al (GCN\n9026).  At this epoch we measure magnitudes of r' = 20.5, i' = 20.0,\nsuggesting the source has faded since the observations reported therein\n(referenced with respected to several nearby SDSS sources).  We therefore\nconfirm this object is the afterglow of GRB090323.",
