GCN Circular 5579
A. Melandri, A. Gomboc, R.J. Smith, N. Tanvir on behalf of the Robonet collaboration report: We imaged the field of GRB 060919 (Guidorzi et al., GCN 5575) with the Faulkes South Telescope starting at 10:36:10.50 UT (about 2.8 hours aftert the burst event). We acquired a first sequence of images in the R-band (6 exposures each lasting 150 seconds) and a second sequence in R and SDSS-I filters (12 exposures lasting 150 seconds in each filter). We did not detect any obvious optical counterpart inside the XRT refined error circle (Guidorzi et al., GCN 5577) down to a limiting magnitude of R > 19.5 (about 2.92 hours after the event). Further analysis and observation are still ongoing.
