Stanek (CfA)  report:\n\nWe again imaged the candidate optical counterpart of GRB000301C\nwith the FLWO 1.2m telescope and R-band filter on 2000 Mar. 4.38 (UT)\nand estimated its magnitude based on the calibration stars\ngiven in GCN 573. We find R=20.56 +/- 0.05 which suggests a rather\nslow decline rate. Using the magnitude estimates from Veillet (GCN 575),\nFynbo et al. (GCN 576), Halpern et al. (GCN 578) and Castro-Tirado et al.\n(GCN 579) we find the data best fit a single power-law index\nof -1.07+\\-0.13 .  However, using data taken since Mar 3.5 (UT) gives\nan even more shallow slope of -0.8 +\\-0.2 and suggests a\npossible flattening of the decay rate.",
