IPN Triangulation of GRB 170626B
Abstract
The long-duration GRB 170626B was detected by Insight (HXMT), Konus-Wind, CALET (CGBM), and Swift (BAT) at about 3482 s UT (00:58:02). The burst was outside the coded field of view of the BAT. We have triangulated it to a Konus-BAT annulus centered at RA(2000)=289.789 deg (19h 19m 09s) Dec(2000)=-19.171 deg (-19d 10' 15"), whose radius is 4.975 ± 4.975 deg (3 sigma). This annulus is inconsistent with the HXMT position reported by Liu et al. (GCN 21265); also, the KW ecliptic latitude response implies the source position close to the ecliptic plane, which is ~30 deg from the HXMT localization. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB170626_T03482/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
