TITLE: GCN CIRCULAR NUMBER: 37026 SUBJECT: IPN triangulation of GRB 240802A / EP 240802a DATE: 24/08/04 13:52:18 GMT FROM: Dmitry Svinkin at Ioffe Institute <svinkin@mail.ioffe.ru> D. Svinkin, D. Frederiks, A. Ridnaia, A. Lysenko, and T. Cline on behalf of the Konus-Wind team, E. Bozzo and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, G. Waratkar, V. Jethwani, J.Joshi, V. Bhalerao, D. Bhattacharya, and S. Vadawale, on behalf of the Astrosat-CZTI team, report: The long-duration GRB 240802A (AstroSat-CZTI detection: Waratkar et al., GCN 37018; SVOM-GRM detection: Wang et al., GCN 37022) was detected by Astrosat (CZTI), Konus-Wind, and INTEGRAL (SPI-ACS), and SVOM (GRM) at about 38044 s UT (10:34:04). We have triangulated it to a preliminary, 3 sigma error region whose area is 394 sq. deg, and its maximum dimension is 51 deg (the minimum one is 6.7 deg). This localization may be improved. The X-ray transient EP 240802a (Wang et al., GCN 37019) is inside the region (at the distance of 0.7 deg from the center line of the Konus-SPI-ACS annulus and 0.4 deg from the center line of Konus-CZTI annulus), supporting the association of the GRB and EP 240802a. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB240802_T38048/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.
