IPN triangulation of GRB 220711C (short)
Abstract
The short-duration GRB 220711C was detected by Fermi (GBM trigger 679248723), INTEGRAL (SPI-ACS), Konus-Wind, and Swift (BAT) at about 58318 s UT (16:11:58). 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: 79.625 -47.309 Corners: 64.292 -35.777 64.270 -36.123 94.188 -53.124 93.862 -52.805 ------------------------------ The error box area is 5.5 sq. deg, and its maximum dimension is 27 deg (the minimum one is 12 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 localization (glg_healpix_all_bn220711675_v00). A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB220711_T58317/IPN The time history and spectrum will be given in forthcoming GCN Circulars.
