Bayliss report on\nbehalf of the UNC team of the FUN GRB Collaboration:\n\nWe observed the afterglow of GRB 050408 (Sakamoto et al., GCN 3189; Wells\net al., GCN 3191; de Ugarte Postigo et al., GCN 3192) with the 4.1-meter\ndiameter SOAR Telescope at CTIO, using the SOAR Optical Imager.\n\nBeginning 9.3 hours after the burst, we observed for 10 x 200 sec in Rc, 9\nx 200 sec in each of V and B, and 9 x 300 sec in U.  The afterglow is well\ndetected in Rc, V, and B.\n\nBetween 9.3 and 10.7 hours after the burst, the Rc light curve faded with a\ntemporal index of -2.23 +/- 0.60.  However, between 10.7 and 13.4 hours\nafter the burst, the temporal index is only -0.54 +/- 0.36.  This suggests\nthat the afterglow was fading rapidly but is now contaminated by a host\ngalaxy.  This confirms the host galaxy identified by Lamb et al. (GCN 3212)\nin the SDSS DR3.\n\nWe are very grateful to the SOAR staff for supporting these observations\nduring SOAR's commissioning period.",
