"The 2-m Faulkes Telescope North robotically followed up GRB 120404A
(Stratta et al., GCN Circ. 13208) at 12:55:03 UT, corresponding to 4 min
after the GRB trigger time. We clearly detect the optical afterglow
candidate by Swift-UVOT (GCN 13208) with a magnitude of 18.8 +- 0.3
in the R filter in a 10-s exposure frame, calibrated against nearby
USNOB-1 field stars.
