Kann (TLS)\nreport on behalf of the Clemson GRB Follow-Up Team:\n\nThe .9m SARA telescope began imaging the field of GRB 070224 approximately\n9 hours after the Swift Trigger 261880 at 20:29:12 UT.  Our observations\nwere comprised of 180-second exposures in the R band.  After stacking 2\nhours worth of exposures, we do not detect any new sources down to a\nlimiting magnitude of R ~ 21.4 +/- 0.4 mag (based on calibration to 10\nfield sources from USNO B1.0 R2 band).\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.",
