on behalf of the REM/ROSS team


We observed the field of GRB 061217 (Barthelmy et al. GCN 5926) with  
the robotic 60-cm REM telescope located at La Silla (Chile). A set of 
observations was performed automatically in the optical and near  
infrared filters (V, R, I and J, H, K, z) starting on 2006 December  17 
at 03:40:56 UT, 35 s after the BAT trigger and 48 s after the GRB  time.

Preliminary analysis of the whole dataset does not show any new  
variable source inside the BAT error box.

The 3-sigma limiting magnitudes are:

   R~18.0
   J~16.0
   H~15.0
   K~13.5
