K. Kinugasa (Gunma Astronomical Observatory) and K. Torii (Osaka U.) report:

 The error region of INTEGRAL GRB 061122 (Mereghetti et al. GCN 5834) was 
imaged by the robotic 0.25m GETS telescope in the Gunma Astronomical 
Observatory. Unfiltered imaging started at 08:46:33 UT (49.1 minutes 
after the trigger) after the end of twilight.

 We did not detect the  optical afterglow (Halpern et al. GCN 5849) and 
the following 3-sigma upper limits are derived relative to USNO-A2.0 R mag.
