Vitali, E. Meurs, P. \nGoldoni, on behalf of the REM/ROSS Team report:\n\n\"We imaged the central part of the field of GRB050509 with the robotic \n60-cm REM telescope located at La Silla, Chile. REM is equipped with \nthe REMIR near infrared camera (10x10 sq arcmin FoV, JHK filters) and \nthe ROSS optical spectrograph/imager (10x10 sq arcmin FoV, VRI filters \nand AMICI prism).\n\nObservations of GRB 050509 were performed in fully automated mode \nsimultaneously in the near infrared and in the optical starting \napproximately 56 seconds after the burst (32 seconds after the \nreception of the burst alert). Then, 2 hrs after the burst, REM \nperformed automatically a further observation of  the refined position \nof GRB 050509 few seconds after the new trigger delivered by the HETE \nTeam.\n\nA preliminary analysis of both the H and R band images does not reveal \nany new object down to the 2MASS and DSS limits respectively.\"\n\nThis message may be cited.",
