Bannister (Leicester) report: "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 position: 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)."
