IPN triangulation of GRB 220219A
Abstract
Report the long-duration GRB 220219A (Fermi-GBM detection: The Fermi GBM team, GCN Circ. 31609; BALROG localization: Kunzweiler et al., GCN Circ. 31610; AGILE-MCAL detection: Ursi et al., GCN Circ. 31611) has been detected by Fermi (GBM trigger 666962499), AGILE (MCAL), Konus-Wind, and Mars-Odyssey (HEND), so far, at about 40894 s UT (11:21:34). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 42.243 (02h 48m 58s) +10.588 (+10d 35' 17") Corners: 43.946 (02h 55m 47s) +6.216 ( +6d 12' 57") 39.857 (02h 39m 26s) +17.180 (+17d 10' 49") 39.457 (02h 37m 50s) +18.548 (+18d 32' 54") 43.844 (02h 55m 23s) +6.598 ( +6d 35' 54") --------------------------------------------- The error box area is 2243 sq. arcmin, and its maximum dimension is 13.1 deg (the minimum one is 3.1 arcmin). The Sun distance was 72 deg. This box may be improved. The IPN localization is consistent with, but reduces the area of, the Fermi GBM Final Real-time position (GCN Circ. 31609) and BALROG (GCN 31610) localizations. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB220219_T40894/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
