Molinari, G. Chincarini, F.M. Zerbi, V. Testa, G. Tosti, F. Vitali, P. Conconi, L.A. Antonelli, G. Cutispoto, G. Malaspina, L. Nicastro, E. Palazzi, E. Meurs, and P. Goldoni 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. This message may be cited.
