Rau, V. Savchenko, E. Bozzo,\nand C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, report:\n\nThe long-duration, very bright GRB 160530A (COSI detection Tomsick GCN \nCirc. 19473) has been detected by Konus-Wind and INTEGRAL (SPI-ACS), so \nfar, at about 25426 s UT (07:03:46).\n\nWe have triangulated it to a Konus-SPI-ACS annulus centered at \nRA(2000)=50.332 deg (03h 21m 20s)  Dec(2000)=+12.855 deg (+12d 51' 19\"), \nwhose radius is 77.066 +/- 0.305 deg (3 sigma).\n\nThe COSI position reported by Tomsick (GCN Circ. 19473) is\nconsistent with the annulus. The annulus combined with the COSI\n(90% confidence) error circle produces the following preliminary error\nbox:\n----------------------------------\nRA(2000), deg   Dec(2000), deg\n----------------------------------\nCenter:\n118.942        -25.764\nCorners:\n118.644        -25.659\n118.758        -26.966\n119.239        -25.868\n119.707        -24.768\n----------------------------------\nThe error box area is 3404.3 sq. arcmin, and its maximum\ndimension is 2.36 deg (the minimum one is 18 arcmin).\nThe Sun distance was about 67 deg.\n\nThis box may be improved.\n\nA triangulation map is posted at\nhttp://www.ioffe.ru/LEA/GRBs/GRB160530_T25426/IPN/\n\nThe Konus-Wind time history and spectrum will be given in a forthcoming\nGCN Circular.",
