S. Vergani, P. D'Avanzo, S.Covino, E. 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 060522 (Fox et al., GCN 5150) with the robotic 60-cm REM telescope located at La Silla (Chile) under mediocre weather conditions. A first set of observations was performed automatically in the near infrared (J, H, K, z bands) starting on May 22.2306 UT (about 3.3 hours after the burst). Then, we took a set of 20x100s H band images starting on May 22.2785 UT (about 4.5 hours the burst).

Preliminary analysis of both the datasets does not show any new source down to H = 16.5 and H=17.0 (3-sigma upper limits) respectively, at the position of the candidate optical afterglow reported by Fox et al. (GCN 5150) and D'Avanzo et al. (GCN 5151).
