IPN triangulation of GRB 240410A

The long-duration GRB 240410A was detected by INTEGRAL (SPI-ACS), Swift (BAT), Konus-Wind, and Mars-Odyssey (HEND) at about 73409 s UT (20:23:29). 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: 109.832 (07h 19m 20s) +30.179 (+30d 10' 43") Corners: 110.414 (07h 21m 39s) +32.327 (+32d 19' 37") 110.411 (07h 21m 39s) +32.546 (+32d 32' 46") 109.265 (07h 17m 04s) +27.655 (+27d 39' 19") 109.268 (07h 17m 04s) +27.350 (+27d 21' 01") --------------------------------------------- The error box area is 957 sq. arcmin, and its maximum dimension is 5.3 deg (the minimum one is 3 arcmin). The Sun distance was 86 deg. This localization may be improved. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB240410_T73409/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
