TITLE: GCN CIRCULAR NUMBER: 32072 SUBJECT: IPN triangulation of GRB 220519A DATE: 22/05/20 20:05:08 GMT FROM: Anna Ridnaia at Ioffe Institute A.S. Kozyrev, D.V. Golovin, M.L. Litvak, I.G. Mitrofanov, and A.B. Sanin on behalf of the HEND/Mars-Odyssey team, A. Ridnaia, D. Frederiks, D. Svinkin, A. Lysenko, and T. Cline on behalf of the Konus-Wind team, E. Bozzo and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, and W. Boynton, C. Fellows, K. Harshman, H. Enos, R. Starr, and A.S. Gardner on on behalf of the GRS-Odyssey GRB team, report: A short-duration GRB 220519A has been detected by Konus-Wind, INTEGRAL (SPI-ACS), and Mars-Odyssey (HEND), so far, at about 42339 s UT (11:45:39). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 357.784 (23h 51m 08s) -9.720 ( -9d 43' 11") Corners: 357.477 (23h 49m 54s) -9.525 ( -9d 31' 30") 357.634 (23h 50m 32s) -10.012 (-10d 00' 45") 358.089 (23h 52m 21s) -9.905 ( -9d 54' 18") 357.931 (23h 51m 43s) -9.420 ( -9d 25' 14") --------------------------------------------- The error box area is 843 sq. arcmin, and its maximum dimension is 43 arcmin (the minimum one is 28 arcmin). The Sun distance was 65 deg. This box may be improved. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB220519_T42339/IPN/ The time history and spectrum will be given in forthcoming GCN Circulars.
