of Los Alamos National Laboratory report:
The RAPTOR network of robotic optical telescopes made follow-up observations
of Swift trigger 548760 (D'Elia, et al., GCN 14204). Our narrow-field
instruments in Los Alamos, NM USA, began imaging at 01:43:07.0 UT, 696.8 s
after the Swift BAT trigger. We detect the optical counterpart initially
reported by the ROTSE team (Zheng, et al., GCN 14205). Our unfiltered images
are calibrated to the USNO-B1 r-band. The following table gives a sample of
our observations.
