TITLE: GCN CIRCULAR NUMBER: 32202 SUBJECT: IPN triangulation of GRB 220606C DATE: 22/06/15 17:58:12 GMT FROM: Dmitry Svinkin at Ioffe Institute A.S. Kozyrev, D.V. Golovin, M.L. Litvak, I.G. Mitrofanov, and A.B. Sanin on behalf of the MGNS/BepiColombo team, J. Benkhoff on behalf of the BepiColombo team, D. Svinkin, D. Frederiks, A. Ridnaia, A. Lysenko, and T. Cline on behalf of the Konus-Wind team, and E. Bozzo and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, report: The long-duration GRB 220606C (CALET-CGBM detection: Nakahira et al., GCN Circ. 32180) was detected by CALET (CGBM), INTEGRAL (SPI-ACS trigger 9949), Konus-Wind, BepiColombo (MGNS), and GECAM-B (trigger tn220606_133517_fb) at about 48918 s UT (13:35:18). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 201.004 (13h 24m 01s) -5.258 ( -5d 15' 29") Corners: 211.181 (14h 04m 43s) +9.433 ( +9d 25' 59") 210.801 (14h 03m 12s) +8.552 ( +8d 33' 07") 200.664 (13h 22m 39s) -22.171 (-22d 10' 16") 200.417 (13h 21m 40s) -23.101 (-23d 06' 03") --------------------------------------------- The error box area is 16.3 sq. deg, and its maximum dimension is 34.2 deg (the minimum one is 28 arcmin). The Sun distance was 125 deg. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB220606_T48919/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
