TITLE: GCN CIRCULAR NUMBER: 13087 SUBJECT: GRB 120320A: Zadko optical observations DATE: 12/03/22 12:16:50 GMT FROM: David Coward at U of Western Aus. D. Macpherson (UWA/ICRAR), D. Coward (UWA), A. Klotz (IRAP-CNRS-OMP), B. Gendre (ASDC/INAF-OAR), M. Todd (Curtin-ICRAR), M. Boer (UNS-CNRS-OCA), A. Williams (PO-UWA), R. Martin (PO-UWA) report: We imaged the field of GRB 120320A detected by SWIFT (trigger 518200) with the UWA Zadko robotic telescope (D=100cm) located at Gingin, Australia. The observations started 6.8 hr after the GRB trigger. The elevation of the field was 49 deg and humid= 63%. 9 images have been maded with a duration of 180.0s each. At the position of the XRT afterglow (Beardmore et al., GCN 13075), we do not detect any source with a limiting magnitude of r = 20.7 on the summed images. The nearest object, which is about 14 arcsec, in our summed image to the XRT location, is a SDSS galaxy (J141005.65+084149.2 ) with a photometric z = 0.34 +- 0.167. This message may be cited.
