report  on behalf of the REM/ROSS team:


We imaged the field of GRB 061222B (Racusin et al. GCN 5957) with  
the  robotic 60-cm REM telescope located at La Silla (Chile). A first  
set  of observations was performed automatically in the optical and  
near infrared (V,R,I and z', J, H, K bands).

A preliminary analysis allows to marginally detect the afterglow  
identified by Berger (GCN 5956) at H ~ 16.0 at 4:14:48 UT.
