TITLE: GCN CIRCULAR NUMBER: 44893 SUBJECT: IPN triangulation of GRB 260601A (short/hard) DATE: 26/06/10 13:06:10 GMT FROM: Dmitry Svinkin at Ioffe Institute <svinkin@mail.ioffe.ru> D. Svinkin, D. Frederiks, A. Lysenko, A. Ridnaia, 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, Zheng-Hang Yu, Chen-Wei Wang, Shao-Lin Xiong, Chao Zheng, Cheng-Kui Li (IHEP) on behalf of GECAM team, C. Wang (IHEP), S. Xiong (IHEP), S. Zhang (IHEP), J. Wei (NAOC), B. Cordier (CEA) on behalf of the SVOM-GRM team, K. Yamaoka (Nagoya U), A. Yoshida, T. Sakamoto, S. Sugita, Y. Kawakubo (AGU), S. Nakahira (JAXA), Y. Asaoka (ICRR), S. Torii, Y.

Marrocchesi (U of Siena), on behalf of the CALET collaboration, report: The short-duration GRB 260601A (Fermi-GBM detection: The Fermi GBM team, GCN 44755; Holzmann Airasca, GCN 44760; Glowbug detection: Cheung et al., GCN 44763; GECAM-B detection: Y. Wang et al., GCN 44778; SVOM-GRM detection: Y. Wang et al., GCN 44793; CALET-GBM detection: Yamaoka et al., GCN 44817) was detected by Fermi (GBM trigger 802004417), CALET (GBM trigger 1464346716), Konus-Wind, Glowbug, SVOM (GRM), and GECAM-B at about 39612 s UT (11:00:12). We have triangulated it to the 3 sigma localization region whose area is 2.8 sq. deg, and its maximum dimension is 73 deg (the minimum one is 2.7 arcmin). A triangulation map and HEALPix FITS files are posted at http://www.ioffe.ru/LEA/GRBs/GRB260601_T39609/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.
