The robotic 60-cm REM telescope located at La Silla (Chile) observed 
automatically the field of the GRB 080207 (Racusin et al., GCN 7264). A 
preliminary analysis of the first set of JHK exposures does not reveal 
any optical afterglow candidate inside the XRT error box (Beardmore et 
al., GCN 7265)  We derive the following 3sigma upper limits (calibrated 
against the 2MASS catalog):

J > 16.7 (7.8 hours after the burst)
H > 15.9 (7.7 hours after the burst)
K > 13.9 (10.1 hours after the burst)
