Wilson-Hodge\non behalf of the Fermi GBM team, report:\n\nThe short-duration, extremely bright GRB 181222B (Veres, GCN 23551)\nwas detected by Fermi (GBM trigger 567202302) and Konus-Wind\nat about 72697 s UT (20:11:37).\n\nWe have triangulated it to a Konus-GBM annulus centered at \nRA(2000)=294.324 deg (19h 37m 18s) Dec(2000)=-23.694 deg (-23d 41' 39\"), \nwhose radius is 51.089 +/- 0.097 deg (3 sigma). The annulus reduces the \narea of the 3 sigma Fermi-GBM final position by about a factor of 130.\n\nThis annulus may be improved.\n\nA triangulation map is posted at\nttp://www.ioffe.ru/LEA/GRBs/GRB181222_T72694/IPN\n\nThe Konus-Wind time history and spectrum will be given in a forthcoming\nGCN Circular.",
