Hartmann (Clemson University) and Todd Hillwig (Valparaiso University) report on behalf of the Clemson GRB Follow-Up Team:\n\n\nThe .9m SARA telescope began imaging the field of INTEGRAL GRB 070311\n(Mereghetti et al., GCN 6189) 1 hour and 10 minutes after the trigger.  The \nobservations were comprised of 180-second and 60-second exposures in the R band.  \nAfter stacking one hour's worth of exposures, we do not detect the afterglow \n(Covino et al. GCN 6190) to a limiting magnitude of 19.6 based\non calibration to 10 field stars from USNO B1.0 R2.\n\nWe thank Jules Halpern for providing a finding chart based on MDM observations.\n\n\nThe Clemson University GRB Response Site may be found at:\nhttp://people.clemson.edu/~kgarime/burst/index.php\n\nThe SARA Homepage can be found at:\nhttp://saraobservatory.org\n\nThis message may be cited.",
