We have derived the following preliminary \n  magnitudes;\n \n  Date, Feb 2001(UT)      R         Texp(s)\n  =========================================\n    23.008--23.012   19.56+-0.03     300\n    23.015--23.019   19.53+-0.03     300\n    23.020--23.023   19.56+-0.03     300\n    23.083--23.086   19.65+-0.03     300\n    23.087--23.091   19.68+-0.03     300\n    23.145--23.148   19.76+-0.03     300\n    23.165--23.167   19.79+-0.05     100\n \n  Our zero-point is based on the the reference star 'A' of McDowell\n  et al. (GCN #963). We have fitted a power-law light curve to the\n  magnitudes reported by  Stanek et al. (GCN #970) and to the ones \n  displayed above. We obtain a value for the slope of 0.86+-0.01\n  (chi^2/dof= 12.7/8=1.6), which is consistent with the one reported\n  by Price et al. (GCN #973)\"",
