York, Report:\n\nWe have obtained one 10-minute exposure in r' and three 10-minute\nexposures in i' of the Beppo-SAX NFI error-box (Gandolfi, GCN 1291) for\nGRB020322 (Piro, GCN 1290) using SPIcam on the ARC 3.5-meter telescope at\nAPO beginning at UTC 9:44 on 2002 March 23.  We estimate the magnitude of\nobject b (Bloom et al., GCN 1296) in our images to be r*=24.5+/-0.7 and\ni*=24.0+/-0.7. We find that object b is now as faint as or fainter than\nobject c (Bloom et al., GCN 1296, Greiner et al., GCN 1298) in both r* and\ni*.  We therefore confirm that the object has faded (Greiner et al., GCN\n1298) and is likely to be the optical afterglow of GRB020322.\n\nThis message is citable.",
