Cobb (GWU), reports:\n\nUsing the ANDICAM instrument on the SMARTS 1.3m telescope at CTIO,\nwe obtained optical imaging of the error region of GRB 110407A\n(GCN 11894, Wolf et al.) with a mid-exposure time of\n2011-04-08 02:12 UT (~12.1 hrs post-burst). The total summed\nexposure time amounted to 36 minutes in I.\n\nNo optical sources is detected at the position of\nthe optical afterglow of GRB 110407A (GCN 11901, Chuang et al.;\nGCN 11904, Malesani et al.; GCN 11906, Kann et al.) to\na limit of I > 20.3.
