K. Torii (Osaka U.) reports:
The error region of the possible GRB 061109 (Falcone et al. GCN 5790)
was observed with the 0.3m telescope in the New Mexico Skies
Observatory. Starting at 261 s after the trigger time, five frames of
120s exposure were acquired through Ic filter. The first frame was
partly saturated and turned out to be useless.
We do not identify a new object within the BAT error circle and
derive the following upper limits relative to USNO-B1.0 I magnitude.
