White, report on behalf of\nthe RAPTOR team.\n  \nStereoscopic observations collected by the RAPTOR wide-field sky\nmonitoring systems allow us to place optical limits on a prompt optical\nflash from GRB 041211 (HETE trigger 3622). Five seconds after receiving\nthe initial HETE type 40 trigger, we began tiling around the nominal\nHETE pointing direction. Our first image containing the GRB location\nbegan at 11:34:09.93 UT (T+143.02s). This image was 10 seconds in\nduration and reached an unfiltered limiting magnitude of 11.5. No new\nobject was detected within the error circle based on comparison to DSS\nimage. Later images reaching 15th magnitude also showed no new objects\ncompared to DSS images.",
