Martin (ESO)\nreport on behalf of a larger collaboration:\n\nWe have observed the afterglow of GRB 110503A (Stamatikos et al.\nGCNC11991) with the Submillimeter Array (SMA, Hawaii, U.S.A.).\nObservations were performed at 217GHz (1.4 mm) using 5 antennas under\nunstable weather conditions (optical depth at 225 GHz ~0.25, humidity\n~50%). The GRB field was observed for 268 minutes (on-source), starting at\n1:15 UT, with mean epoch on 4 May at 5:36 UT, 12.0 hours after the burst.\nWe do not detect any significant flux at the position of the optical\nafterglow, imposing a 3-sigma detection limit of 5.1 mJy.\n\n[GCN OPS NOTE(05may11): Per author's request, the burst name\nin the Subject-line was corrected.]",
