IPN triangulation of GRB 211106A (short)
Abstract
The short-duration GRB 211106A (Swift-BAT-GUANO detection: Tohuvavohu et al., GCN 31049; Konus-Wind detection: Ridnaia et al., GCN 31054; Fermi-GBM sub-threshold detection: Fletcher et al., GCN 31055) was detected by INTEGRAL (SPI-ACS), Swift (BAT), Konus-Wind, and Fermi (GBM) at about 16651 s UT (04:37:31). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 342.487 (22h 49m 57s) -52.039 (-52d 02' 19") Corners: 359.734 (23h 58m 56s) -61.384 (-61d 23' 04") 333.528 (22h 14m 07s) -40.998 (-40d 59' 52") 331.989 (22h 07m 57s) -42.431 (-42d 25' 51") 0.415 (00h 01m 40s) -63.951 (-63d 57' 05") --------------------------------------------- The error box area is 45.2 sq. deg, and its maximum dimension is 27.7 deg (the minimum one is 1.7 deg). The Sun distance was 95 deg. The Swift-BAT position reported in Tohuvavohu et al. is consistent with the IPN error box. This box may be improved. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB211106_T16652/IPN/ The Swift (BAT) event data used for the IPN localization came from the GUANO system (https://www.swift.psu.edu/guano/).
