GCN Circular 12081
B. E. Cobb (GWU), reports: Using the ANDICAM instrument on the SMARTS 1.3m telescope at CTIO, we obtained optical imaging of part of the error region of GRB 110618A (GCN 12077, Hurley et al.) approximately 113 hours (4.7 days) post-burst. Nine individual 5-minute I-band exposures were obtained, tiled around the center of the IPN error region (RA/Dec: 11h47m14s -71d41'16"). Each image is 6'x6', so these images cover approximately 0.09 square degrees, e.g. the central 6% of the IPN error region. Preliminary visual comparison to the DSS reveals no new optical sources in the SMARTS images (limited by the slightly shallower depth of the DSS imaging). This does not rule out the possibility of an afterglow candidate contained in a relatively bright host galaxy (additional SMARTS imaging is being obtained for further analysis).
