TITLE: GCN CIRCULAR NUMBER: 35710 SUBJECT: IPN triangulation of GRB 240205A (short) DATE: 24/02/09 16:02:13 GMT FROM: Dmitry Svinkin at Ioffe Institute D. Svinkin, D. Frederiks, A. Ridnaia, A. Lysenko, and T. Cline on behalf of the Konus-Wind team, A. Goldstein, M. S. Briggs, C. Wilson-Hodge, and E. Burns on behalf of the Fermi GBM team, E. Bozzo and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, and S. Barthelmy, J. Cummings, H. Krimm, D. Palmer, and A. Tohuvavohu on behalf of the Swift-BAT team, report: The short-duration GRB 240205A (Ferm-GBM detection: The Fermi GBM team, GCN 35679; Glowbug detection: Cheung, et al., GCN 35707) was detected by Fermi (GBM trigger 728857595), Konus-Wind, INTEGRAL (SPI-ACS), and Swift (BAT) at about 73591 s UT (20:26:31). The burst was outside the coded field of view of the BAT. We have triangulated this GRB to the following annuli: --------------------------------------------------- annulus R.A. Dec. R dR (3sigma) (deg) (deg) (deg) (deg) --------------------------------------------------- Konus-GBM 297.778 -19.219 40.665 0.735 GBM-SPI-ACS 180.960 84.546 70.289 6.208 --------------------------------------------------- The annuli intersect to form a long 60.9 sq.deg (3 sigma) localization region. This localization may be improved. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB240205_T73586/IPN The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
