TITLE: GCN CIRCULAR NUMBER: 25334 SUBJECT: IPN triangulation of GRB 190813A (short) DATE: 19/08/15 10:43:27 GMT FROM: Dmitry Svinkin at Ioffe Institute D. Svinkin and K. Hurley, on behalf of the IPN, A. Goldstein, M. S. Briggs, and C. Wilson-Hodge on behalf of the Fermi GBM team, and A. von Kienlin, X. Zhang, A. Rau, V. Savchenko, E. Bozzo, and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, report: The short-duration GRB 190813A (The Fermi GBM team, GCN Circ. 25317) was detected by Fermi (GBM trigger 587392154) and INTEGRAL (SPI-ACS), at about 44950 s UT (12:29:10). We have triangulated this GRB to a GBM-INTEGRAL annulus centered at RA(2000)=96.795 deg (06h 27m 11s) Dec(2000)=-39.989 deg (-39d 59' 21"), whose radius is 23.630 +/- 8.231 deg (3 sigma). The IPN localization is consistent with, but reduces the area of, the Fermi-GBM one. This annulus may be improved. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB190813_T44949/IPN/
