TITLE: GCN CIRCULAR NUMBER: 42614 SUBJECT: IPN triangulation of GRB 251105B (possible sGRB with EE) DATE: 25/11/07 15:12:08 GMT FROM: Dmitry Svinkin at Ioffe Institute <svinkin@mail.ioffe.ru> A.S.

Burns on behalf of the Fermi GBM team, and W. Boynton, C. Fellows, K. Harshman, H. Enos, R. Starr, and A.S. Gardner on on behalf of the GRS-Odyssey GRB team, report: The possible short-duration GRB with extended emission GRB 251105B (SVOM-GRM detection: Wang et al., GCN 42586; Fermi-GBM detection: Hamburg eat al., GCN 42589; AstroSat-CZTI detection: Harsha et al., GCN 42591) was detected by SVOM (GRM), Konus-Wind, Fermi (GBM), AstroSat (CZTI), and Mars-Odyssey (HEND) at about 3514 s UT (00:58:34). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 277.814 (18h 31m 15s) +9.028 ( +9d 01' 39") Corners: 277.022 (18h 28m 05s) +9.993 ( +9d 59' 36") 277.294 (18h 29m 11s) +9.729 ( +9d 43' 46") 278.607 (18h 34m 26s) +8.012 ( +8d 00' 43") 278.333 (18h 33m 20s) +8.303 ( +8d 18' 10") --------------------------------------------- The error box area is 362 sq. arcmin, and its maximum dimension is 2.5 deg (the minimum one is 3 arcmin). The Sun distance was 62 deg. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB251105_T03511/IPN The HEALPix triangulation map is the multi-order HEALPix in units of probability density. The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
