Milne (Steward Observatory), on behalf of\nthe Super-LOTIS Collaboration, report:\n\nThe robotic 0.6-m Super-LOTIS telescope began observing the error box of\nGRB 071011 (Swift Trigger 293924, Marshall et al. GCN 6882) at 12:40:53.4 UT,\n40.4 seconds after the trigger.  Our initial observations include 5 x 10s\nexposures, 5 x 20s exposures, and 30 x 60s exposures, all in the R-band.\n\nThe observations occurred during morning twilight at a starting airmass\nof 2.16.  In our earliest exposure, we do not detect the afterglow\ncandidate reported by Perley (GCN 6883) and confirmed by Iizuka (GCN 6886)\nor any other candidates in the BAT error circle to the following\n3-sigma limiting magnitude determined from nearby USNO-B1.0 stars:\n\nt_start (UT)    exp t (s)       t_start-t_0 (s) Limit\n--------------------------------------------------------\n12:40:53.4      10.0            40.4            R > 16.90\n\nSubsequent exposures also do not reveal any additional candidates.\nAnalysis is ongoing.",
