Hartmann (Clemson University) report \non behalf of the Clemson GRB Follow-Up Team:\n\nWe used the 0.9m SARA telescope on Kitt Peak to image the field of GRB \n070520B (GCN 6425, Moretti et al.) under decent weather conditions \nbeginning 9.5 hours after the burst trigger (279898).  In 52 minutes of \nstacked R-band exposures, we detect no new sources down to a limiting \nmagnitude of 20.2 +/- 0.4 based on calibration to 8 USNO B1.0 stars.\n\nThe SARA Homepage can be found at:\n http://saraobservatory.org\n\nThis message may be cited.",
