IPN triangulation of GRB 200111A
Abstract
The long-duration GRB 200111A (The Fermi GBM team, GCN Circ. 26705; Insight-HXMT/HE detection: Xiao et al., GCN Circ. 26714) was detected by Konus-Wind, Fermi (GBM trigger 600448273), INTEGRAL (SPI-ACS), Mars-Odyssey (HEND), Insight (HXMT/HE), and Swift (BAT) at about 54668 s UT (15:11:08). The burst was outside the coded field of view of the BAT. We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 107.869 (07h 11m 29s) +32.551 (+32d 33' 03") Corners: 107.545 (07h 10m 11s) +34.162 (+34d 09' 42") 107.747 (07h 10m 59s) +34.483 (+34d 28' 58") 108.134 (07h 12m 32s) +30.686 (+30d 41' 10") 107.920 (07h 11m 41s) +30.214 (+30d 12' 52") --------------------------------------------- The error box area is about 2864 sq. arcmin, and its maximum dimension is 4.3 deg (the minimum one is 12.2 arcmin). The Sun distance was about 167 deg. This box may be improved. The IPN localization is consistent with, but reduces the area of, the Fermi-GBM one. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB200111_T54677/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
