TITLE: GCN CIRCULAR NUMBER: 16427 SUBJECT: IPN Triangulation of GRB 140619C (long/very intense) DATE: 14/06/21 10:29:40 GMT FROM: Dmitry Svinkin at Ioffe Institute K. Hurley and J. Goldsten, on behalf of the MESSENGER NS GRB team, I. G. Mitrofanov, D. Golovin, M. L. Litvak, and A. B. Sanin, on behalf of the HEND-Odyssey GRB team, S. Golenetskii, R. Aptekar, V. Pal'shin, D. Frederiks, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, A. von Kienlin, X. Zhang, A. Rau, V. Savchenko, E. Bozzo, and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, and K. Yamaoka, M. Ohno, Y. Hanabata, Y. Fukazawa, T. Takahashi, M. Tashiro, Y. Terada, T. Murakami, and K. Makishima on behalf of the Suzaku WAM team, report: The long-duration, very intense GRB 140619C has been observed by Konus-Wind, MESSENGER (GRNS), Mars-Odyssey (HEND), INTEGRAL (SPI-ACS), and Suzaku (WAM), so far, at about 81966 s UT (22:46:06). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 233.018 (15h 32m 04s) -25.599 (-25d 35' 55") Corners: 233.298 (15h 33m 12s) -25.530 (-25d 31' 48") 232.810 (15h 31m 14s) -26.672 (-26d 40' 18") 232.738 (15h 30m 57s) -25.666 (-25d 39' 56") 233.252 (15h 33m 00s) -24.382 (-24d 22' 57") --------------------------------------------- The error box area is 0.549 sq. deg, and its maximum dimension is 2.3 deg (the minimum one is 0.426 deg). This box may be improved. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB140619_T81966/IPN/ The time history and spectrum will be given in a forthcoming GCN Circular.
