Skynet observed the localization of GRB 081203A (Parsons et al., GCN 8595)
with the 14" GORT telescope at Hume Observatory in California beginning 122
seconds after the trigger (101 seconds after notification) in RI.
Only five exposures were taken before morning twilight. We detect the
afterglow (Parsons et al., GCN 8595) in all five exposures. Calibrated to
five USNO B1 stars, we find:
