GCN Circular 8475
A. Melandri, D.F. Bersier, M. Burgdorf, C.G. Mundell, R.J. Smith, I.A. Steele (Liverpool JMU) on behalf of a larger collaboration report: On 2008 November 04 on 12:13 UT we observed the field of GRB 081104 (trigger = 333666, Parsons et al., GCN 8473) with the robotic 2m Faulkes Telescope South located in Australia. We do not detect any fadind optical source within the XRT error circle (Mangano et al., GCN 8474) down to the following limit: Dt_mid T_exp Filter Mag_lim [hr] [min] =========================================== 2.89 30.0 R > 21.9 =========================================== Limiting magnitude has been estimated using the R2 magnitude of the USNO-B1 catalogue. The reported value is not corrected for the Galactic extinction.
