TITLE: GCN CIRCULAR NUMBER: 24497 SUBJECT: IPN triangulation of GRB 190510A (short) DATE: 19/05/12 07:36:44 GMT FROM: Anna Kozlova at Ioffe Institute A. Kozlova, S. Golenetskii, R. Aptekar, D. Frederiks, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, K. Hurley, on behalf of the IPN, A. Goldstein, M. S. Briggs, and C. Wilson-Hodge on behalf of the Fermi GBM team, and S. Barthelmy, J. Cummings, H. Krimm, and D. Palmer, on behalf of the Swift-BAT team, report: The short-duration GRB 190510A was detected by Fermi (GBM trigger 579176361), Konus-Wind, and Swift (BAT) at about 37156 s UT (10:19:16). The burst was outside the coded field of view of the BAT. We have triangulated this GRB to a Konus-GBM annulus centered at RA(2000)=34.022 deg (02h 16m 05s) Dec(2000)=+13.078 deg (+13d 04' 42"), whose radius is 89.425 +/- 0.966 deg (3 sigma). The annulus is inconsistent with the GW compact binary merger candidate event S190510g (The LIGO Scientific Collaboration and the Virgo Collaboration GCN Circ. 24442). This annulus may be improved. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB190510_T37156/IPN/ The time history and spectrum will be given in forthcoming GCN Circulars.
