Pizzichini (IASF-CNR, Sezione di Bologna)\nand R. McNaught (RSAA, ANU) report:\n\nWe observed the SXC error-circle of GRB 020819 (GCN #1508) with the\nPalomar 60-inch telescope at Aug 20.34 UT with 4x600 sec exposures in R.\nComparison of this combined image with those from the SSO 40-inch\ntelescope (GCN #1506) and the Loiano 1.5-metre telescope (GCN #1509),\nboth visually and through image subtraction do not reveal any afterglow\ncandidates.  We estimate the limiting magnitudes to be as follows:\n\nSSO 40-inch\t\tR ~ 20.5 mag\t(GCN #1506)\nLoiano 1.5-metre\tR ~ 21.7 mag\t(GCN #1509)\nPalomar 60-inch\t\tR ~ 21.5 mag\n\nComparison of the best NIR afterglow candidate (GCN #1510) with other\nsources in the field suggests that this candidate is likely constant in\nflux.\n\nThis message may be cited.",
