Starting at Sep.27 14:44:33 UT (37 min after \nthe burst), thirty 30 s exposures in Rc band were obtained.\n\n In a stacked frame, the optical afterglow (Schaefer et al. GCN 5629) is\ndetected and the magnitude is rouly estimated as follows relative to \nUSNO-B1.0 R2 magnitude. \n\n------------------------\nMidUT   Filter  Mag\n------------------------\n14:56   Rc      ~20.3\n------------------------",
