We observed the field of the GRB 071010 (Moretti et al., GCN 6859)  with 
the robotic 60-cm REM telescope located at La Silla (Chile). A set of 
observations was performed automatically in the Z, J, H, K NIR filters 
starting at 03:42:52 UT (about 100 sec after the burst) and lasted about 
30 minutes due to visibility constraints.

The analysis of the first set of H-band exposures clearly show the 
optical afterglow candidate reported by Klotz et al. (GCN 6860), Bloom 
et al. (GCN. 6861), Haislip et al. (GCN. 6862) at a level of H =14.3 ± 
0.2 (calibrated against the 2MASS catalog). The afterglow is clearly 
detected in all bands.

Futher analysis is in progress.
