Martin Ruiz, I. de Gregorio (ALMA), \nS. Kim (PUC), R. S��nchez-Ramirez (INAF-IAPS), \nD. Malesani (DARK/NBI) report:\n\nWe observed the afterglow of GRB 171205A with \nNOEMA at 150GHz and 90GHz starting at 3:30 UT on the \n6th of December (20.2 hrs after the GRB onset). We \ndetect a bright afterglow in 150GHz with a preliminary \nflux density estimate of 35-40 mJy. The coordinates \nof the detected source are (J2000 +/- 0.05\"):\n\nR.A.: 11:09:39.52\nDec.: -12:35:18.34\n\nWe note that if the flux density is confirmed, it would be \nthe second brightest GRB ever detected in mm/submm \nwavelengths, after GRB 030329 (for a review on \nmm/submm data of GRBs see de Ugarte Postigo et al. \n2012).\n\nFurther follow-up observations are encouraged.",
