T. Sakamoto (UMBC/GSFC), Y. Urata (Saitama U), D. Donato (ORAU/GSFC), N. Gehrels (GSFC), T. Okajima (JHU/GSFC), T. N. Ukwatta (GWU/GSFC) We observed the field of GRB 081126 detected by Swift (trigger #335647) with the 14-inch Goddard Robotic Telescope (GRT) located at the Goddard Geophysical and Astronomical Observatory (http://cddisa.gsfc.nasa.gov/ggao/). Five set of 30s and 60s exposures were taken in the R filter starting from Nov. 27 03:58:18 (UT). We do not detect any OT at the XRT position (Osborne et al. 2008 GCNC 8556). The estimated 3-sigma upper limit of the combined image is ~17.5 mag using the USNO-B (r) catalog.
