"The 2-m Faulkes Telescope North followed up GRB060204B
(SWIFT trigger 180241) 46.2  min after the GRB trigger time.
We detect a new source in R and i' filters not present in the
SDSS pre-burst images (Cool et al., GCN 4657) at the following

14:07:14.9   27:40:36.4    (J2000)

with a magnitude R = 20.4 +- 0.4 mag (vs USNOB1), from 46.2 min to 57.0
min after the burst, and i'=20.1 +- 0.3 (vs SDSS i' band image),
from 53.2 min to 58.8 min after the burst trigger time.
The source lies inside the XRT error circle (Falcone et al. GCN 4655)."
