  "body": "The candidate for the optical transient (OT) associated with the gamma \nray burst  GRB000301C has been observed using the CFH12K CCD mosaic \ncamera at the prime focus of the 3.6-m CFH Telescope in the course of \nthe French GRB  follow-up  program at CFHT (M. Boer, CESR,  C. Veillet, \nCFHT). \n\nThree 12 mn exposures with moderate seeing (image quality around 0.9\") have\nbeen coadded.\n\nThere is nothing visible at the location of the OT. The nearby galaxy \n(thought to be the host for some time before the HST observations) has a \nmagnitude of R= 24.5 +-0.1, confirming the previous determinations (GCN592 \n- GCN598).\nThe faintest objects detected in the neighborhood are at around R=26.\n\nWe can infer the following lower limit:\nR > 26.0 on 2000 April 4.6 \n\nIt is compatible with the alpha = -2.7 power law decay given in GCN611, and \nnot with alpha  = -2.1 given earlier, which would lead to R~25.6 at the\nsame epoch.\n\nFurther imaging is planned if the seeing gets better.\n\nJean-Charles Cuillandre is acknowledged for his help in this observation. \n\nThis message may be cited. \n\n\n\n-- \n************************************************************\nDr. Christian Veillet,       CFHT Senior Resident Astronomer\nPhone: (808) 885-3161   http://www.cfht.hawaii.edu/~veillet/\n************************************************************",
