TITLE: GCN CIRCULAR NUMBER: 36872 SUBJECT: IPN triangulation of GRB 240715A (short) DATE: 24/07/15 15:46:04 GMT FROM: Anna Ridnaia at Ioffe Institute <ridnaia@mail.ioffe.ru> A.S. Kozyrev, D.V. Golovin, M.L. Litvak, I.G. Mitrofanov, and A.B. Sanin on behalf of the HEND/Mars Odyssey team, A. Ridnaia, D. Frederiks, A. Lysenko, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, A. Goldstein, M. S. Briggs, C. Wilson-Hodge, and E. Burns on behalf of the Fermi GBM team, E. Bozzo and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB 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 short-duration GRB 240715A (Fermi-GBM detection: The Fermi GBM team, GCN 36866) was detected by Fermi (GBM trigger 742715048), Konus-Wind, INTEGRAL (SPI-ACS), and Mars-Odyssey (HEND) at about 20642 s UT (05:44:02). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 5.271 (00h 21m 05s) -36.521 (-36d 31' 16") Corners: 5.188 (00h 20m 45s) -36.486 (-36d 29' 11") 5.394 (00h 21m 35s) -36.672 (-36d 40' 20") 5.354 (00h 21m 25s) -36.556 (-36d 33' 22") 5.148 (00h 20m 36s) -36.369 (-36d 22' 09") --------------------------------------------- The error box area is 48 sq. arcmin, and its maximum dimension is 22 arcmin (the minimum one is 3 arcmin). The Sun distance was 118 deg. The IPN localization is consistent with, but reduces the area of, the Fermi-GBM final localization. Swift ToO has been submitted. This localization may be improved. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB240715_T20645/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.
