//////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2387 SUBJECT: IPN triangulation of GRB030916 (possible short/hard GRB; large error box) DATE: 03/09/17 17:55:25 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley and T. Cline, on behalf of the Ulysses, Mars Odyssey, and KONUS GRB teams, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, I. Mitrofanov, S. Charyshnikov, V. Grinkov, A. Kozyrev, M. Litvak, and A. Sanin, on behalf of the HEND-Odyssey GRB team, W. Boynton, C. Fellows, K. Harshman, C. Shinohara and R. Starr, on behalf of the GRS-Odyssey GRB team, and A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, report: Konus-Wind, Mars Odyssey-HEND, and INTEGRAL SPI-ACS observed this burst at 79159 s. As observed by INTEGRAL, it had a duration of approximately 1 second. This burst appears to be in the short-hard category. We have triangulated it to a preliminary, 3 sigma error box whose area is approximately 1500 sq. arminutes and whose coordinates are: RA(2000) DEC(2000) 8 h 43 m 42.90 s -48 o 53 ' 57.38 " (CENTER) 8 h 52 m 58.66 s -49 o 35 ' 34.81 " (CORNER) 8 h 53 m 20.75 s -49 o 28 ' 54.32 " (CORNER) 8 h 34 m 22.50 s -48 o 15 ' 5.44 " (CORNER) 8 h 34 m 46.40 s -48 o 8 ' 39.98 " (CORNER) This error box may be improved, but as this event was not observed by Ulysses, a small error box cannot be obtained for it.
