Tamagawa (RIKEN) report: "WIDGET has continuously monitored the entire error region of the GRB 060211A (Hurkett et al. GCN 4736, 4740) with repeat of unfiltered 5-second exposures during the night of 11th February. The 1-sigma limiting magnitude of images taken between 792 seconds before and 321 seconds after the burst was around V=10.8 magnitude. The magnitude was derived by the Tycho-2 catalog. There was no significant emission from the X-ray afterglow position up to the limiting magnitudes." This message maybe cited.
