Krzeminski (LCO) report:\n\n\"We observed the BAT error circle of GRB 070920b (GCN 6808) with the Swope \n40-inch telescope at Las Campanas Observatory starting on 2007 Sep. 21.22 \nUT (8.2 hours after the burst).  A total of 30 minutes were obtained in \nR-band in mediocre seeing conditions (~1.5\").  A comparison to DSS reveals \nno new objects within the revised BAT error circle (GCN 6811).\"",
