TITLE: GCN CIRCULAR NUMBER: 45208 SUBJECT: IPN triangulation of GRB 260706B DATE: 26/07/24 16:54:10 GMT FROM: Dmitry Svinkin at Ioffe Institute <svinkin@mail.ioffe.ru> A.S. Kozyrev, D.V. Golovin, M.L. Litvak, I.G. Mitrofanov, A.B. Sanin, and J. Benkhoff on behalf of the MGNS/BepiColombo and HEND/Mars-Odyssey teams, G. Jones on behalf of the BepiColombo team, D. Svinkin, D. Frederiks, A. Lysenko, A. Ridnaia, and T. Cline on behalf of the Konus-Wind team, D.J. Lawrence, J.O. Goldsten, P.N. Peplowski on behalf of the Psyche/GRNS team, E. Burns on behalf of the IPN, W. Boynton, C. Fellows, K. Harshman, H. Enos, R. Starr, and A.S. Gardner on on behalf of the GRS-Odyssey GRB team report: The long-duration GRB 260706B was detected by Konus-Wind, Psyche (GRNS), Mars-Odyssey (HEND), and BepiColombo (MGNS) at about 84082 s UT (23:21:22). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: The correct preliminary 3-sigma error box is: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 130.509 (08h 42m 02s) +16.967 (+16d 58' 00") Corners: 130.752 (08h 43m 01s) +17.921 (+17d 55' 14") 130.743 (08h 42m 58s) +17.692 (+17d 41' 30") 130.183 (08h 40m 44s) +15.751 (+15d 45' 04") 130.232 (08h 40m 56s) +16.102 (+16d 06' 06") --------------------------------------------- The error box area is 352 sq. arcmin, and its maximum dimension is 2.2 deg (the minimum one is 3 arcmin). The Sun distance was 24 deg. This localization may be improved, as soon as the Psyche (GRNS) timing accuracy will be analyzed. A triangulation map and HEALPix FITS files are posted at http://www.ioffe.ru/LEA/GRBs/GRB260706_T84082/IPN The HEALPix triangulation map is the multi-order HEALPix in units of probability density. The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
