Milne (Steward Observatory), G. G. Williams (MMTO), and D. H. Hartmann (Clemson) report on behalf of the Super-LOTIS Collaboration: The robotic 0.6m Super-LOTIS telescope observed the field of GRB 071010B (GCN 6871, Markwardt et al.) beginning at 10:24 UT on Oct 11, 13.6 hours after the trigger. We obtained 59 minutes in the R band and 19 minutes in the V band. We do not detect the OT (Oksanen GCN 6873, Kann et al. GCN 6884) in the stacked exposures. Limiting magnitudes were determined using 10 field stars calibrated to the USNO B1.0 catalog. t_start (UT) Filter exp (s) Limit ------------------------------------------------------------- 10:24:40 R 59x60 > 20.4 10:49:00 V 19x60 > 19.2 This message may be cited.
