Vitali, report on behalf of the REM team:\n\nThe robotic 60-cm REM telescope located at La Silla (Chile) observed  \nautomatically the field of the GRB 080413A (Beardmore et al., GCN  \n7594) starting about 1.3 hours after the burst due to object  \nvisibility constraints.\nObservation started as soon as the object is risen so the Airmass was  \nlarge.\n\nA preliminary investigation of our earliest images (R,z,J,H,K) showed  \nthat the candidate optical counterpart (Rykoff et al. GCN 7593,  \nBeardmore et al., GCN 7594, Klotz et al., GCN 7595) is observed in  \nall bands. At the beginning of REM observation, the object had a H  \nmag of about H=15.2 calibrated against 2MASS and not corrected for  \ngalactic extinction.\n\nThis message may be cited.",
