Melandri (INAF-OAB) report: "The 2-m Faulkes Telescope South responded robotically to followup GRB120211A (SWIFT trigger 514586; Sonbas et al. GCN 12920) 3.77 min after the GRB trigger time. No optical counterpart within the XRT error circle is detected to the following conservative limits: R > 21.5 mag (vs USNOB1) at 0.51 hrs from BAT trigger (total exposure = 720 s) i' > 20.4 mag (vs USNOB1) at 0.58 hrs from BAT trigger (total exposure = 700 s) We also note the presence of a USNOB-1 object lying on the XRT error circle border: 05:51:00.786, -24:46:23.86, with R2=20.19 and I=18.74 mag This message may be cited"
