IPN triangulation of GRB 230723A (short)
Abstract
Report the short-duration GRB 230723A (Fermi GBM detection: The Fermi GBM team, GCN 34232; AGILE/MCAL detection: Panebianco et al., GCN 34237) has been detected by Fermi (GBM), Konus-Wind, AGILE (MCAL, AC), and Mars-Odyssey (HEND), so far, at about 16723 s UT (04:38:43). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 22.909 (01h 31m 38s) -67.059 (-67d 03' 31") Corners: 24.618 (01h 38m 28s) -66.230 (-66d 13' 48") 24.638 (01h 38m 33s) -66.276 (-66d 16' 34") 21.066 (01h 24m 16s) -67.859 (-67d 51' 31") 21.054 (01h 24m 13s) -67.813 (-67d 48' 46") --------------------------------------------- The error box area is 265 sq. arcmin, and its maximum dimension is 2.1 deg (the minimum one is 2 arcmin). The Sun distance was 111 deg. The IPN localization is consistent with, but reduces the area of, the Fermi-GBM final localization (GCN 34232). This localization may be improved. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB230723_T16725/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
