E. Berger (Princeton,OCIW) and W. Krzeminski (LCO) report:
"We observed the BAT error circle of GRB 070920b (GCN 6808) with the Swope
40-inch telescope at Las Campanas Observatory starting on 2007 Sep. 21.22
UT (8.2 hours after the burst). A total of 30 minutes were obtained in
R-band in mediocre seeing conditions (~1.5"). A comparison to DSS reveals
no new objects within the revised BAT error circle (GCN 6811)."
