Tovmassian, OAN IA\nUNAM, Mexico, report:\n\nWe observed GRB 000301C optical counterpart in the R band on March\n4.458 UT using the 2.1m  telescope of the \"Guillermo Haro\" Observatory in\nCananea, Sonora, Mexico with the Landessternwarte Faint Object\nSpectrograph and Camera (LFOSC). Using reference  stars A-D of Garnevich\net al. (GCN 573), we derive  R-band magnitude of  R = 20.54+\\-0.06 for\nthe OT at 2000 March 4.458 UT. This magnitude is in a good agreement\nwith other observations that were obtained approximately at the  same\ntime (GCN #581, 582, 593).\n\nThis message may be cited.\n\n\n[GCN OPS NOTE:  This submission was delayed several hours because of a\nchange in the submitor's address.]",
