IPN triangulation of GRB 220128A (long)
Abstract
The long-duration GRB 220128A was detected by Konus-Wind, Swift (BAT), INTEGRAL (SPI-ACS), and Mars-Odyssey (HEND) at about 11897 s UT (03:18:17). 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: 350.191 (23h 20m 46s) -49.734 (-49d 44' 02") Corners: 349.616 (23h 18m 28s) -46.520 (-46d 31' 11") 350.856 (23h 23m 25s) -52.699 (-52d 41' 57") 350.687 (23h 22m 45s) -52.865 (-52d 51' 53") 349.478 (23h 17m 55s) -46.702 (-46d 42' 08") --------------------------------------------- The error box area is 2688 sq. arcmin, and its maximum dimension is 6.38 deg (the minimum one is 7 arcmin). The Sun distance was 42 deg. This box may be improved. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB220128_T11896/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
