Garnavich (Notre Dame) report:\n\nR-band observations of the optical afterglow of the GRB011121 carried\nout with the OGLE 1.3m telescope (+8kx8k OGLE-III mosaic) at the Las\nCampanas Observatory, starting at UT 011122 05:08 (10.3 hours after\nthe burst), reveal a new, bright source in the refined BeppoSAX-WFC\nerror box (GCN 1149). Its position, based on the GSC, is: 11:34:30.38,\n-76:01:41.3 (J2000).\n\nComparing to star \"A\" (R=17.4) from the USNO catalog (located at\n11:34:18.9, -76:01:38.1, J2000), we estimate the R-band magnitude of\nthe possible GRB011121 afterglow to be R=18.3\\pm 0.1 (subject to\npossible systematic error due to the calibration of the catalog).\n\nAdditional data will be obtained.\n\nThe E(B-V) Galactic reddening from Schlegel et al. is E(B-V)=0.5, or\nA_R=1.33.\n\nThis message can be cited.",
