IPN triangulation of GRB 211130A
Abstract
Report: The long-duration GRB 211130A (Fermi GBM Final Real-time localization: The Fermi GBM team, GCN 31151; BALROG localization: Kunzweiler et al., GCN 31152) was detected by Fermi (GBM trigger 659978192), Konus-Wind, INTEGRAL (SPI-ACS), and BepiColombo (MGNS) at about 54987 s UT (15:16:27). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 21.148 (01h 24m 35s) -27.829 (-27d 49' 46") Corners: 20.183 (01h 20m 44s) -27.190 (-27d 11' 25") 20.317 (01h 21m 16s) -27.403 (-27d 24' 10") 22.106 (01h 28m 25s) -28.433 (-28d 25' 58") 21.973 (01h 27m 54s) -28.233 (-28d 13' 58") --------------------------------------------- The error box area is 734 sq. arcmin, and its maximum dimension is 2.1 deg (the minimum one is 6.5 arcmin). The Sun distance was 113 deg. This box may be improved. The IPN localization is consistent with, but reduces the area of, the Fermi final position and BALROG localizations. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB211130_T54992/IPN The time history and spectrum will be given in forthcoming GCN Circulars.
