IPN triangulation of GRB 230803A
Abstract
Report the long-duration GRB 230803A (Fermi GBM detection: Fermi GBM team, GCN 34325; AstroSat CZTI detection: Navaneeth et al., GCN 34328) has been detected by Fermi (GBM), Konus-Wind, INTEGRAL (SPI-ACS), AstroSat (CZTI), and Mars-Odyssey (HEND), so far, at about 5228 s UT (01:27:08). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 150.510 (10h 02m 02s) -64.987 (-64d 59' 12") Corners: 147.455 (09h 49m 49s) -64.554 (-64d 33' 15") 147.329 (09h 49m 19s) -64.581 (-64d 34' 51") 153.688 (10h 14m 45s) -65.347 (-65d 20' 50") 153.812 (10h 15m 15s) -65.315 (-65d 18' 54") --------------------------------------------- The error box area is 431 sq. arcmin, and its maximum dimension is 2.8 deg (the minimum one is 3 arcmin). The Sun distance was 83 deg. The IPN localization is consistent with, but reduces the area of, the Fermi-GBM final localization (GCN 34325). This localization may be improved. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB230803_T05229/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
