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.
