Figueredo report on behalf of the UNC team of the FUN GRB\nCollaboration.\n\nWe continued observations of the afterglow (Haislip et al., GCN 3913) of\nGRB 050904 (Cummings et al., GCN 3910) with 4.1m SOAR at CTIO in J,\nbeginning 52.9 hours after the burst.\n\nThe afterglow is no longer detected: J > 21.6 (2 sigma).  This implies that\ntemporal index has steepened from -1.0 +/- 0.1 (Haislip et al., GCN 3919)\nto <-2.3 over the past day, which suggests that we are now past the\njet-break time.",
