TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1454 SUBJECT: IPN triangulation of GRB150702 DATE: 02/07/17 16:06:36 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley and T. Cline, on behalf of the Ulysses, Mars Odyssey, and Konus-Wind GRB teams, I. Mitrofanov, D. Anfimov, 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 E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, report: Ulysses, Konus-Wind, and MO-HEND observed this burst at 69663 s. As observed by Ulysses, it had a duration of approximately 10 seconds, a 25-100 keV fluence of approximately 1.3E-05 erg/cm2, and a peak flux of approximately 3.0E-06 erg/cm2 s over 0.25 seconds. We have triangulated it to two alternate preliminary 3 sigma error boxes whose approximate areas are 140 sq. arcmin. each and whose coordinates are: RA(2000) DEC(2000) ERROR BOX CENTER: 13 h 50 m 12.66 s 61 o 50 ' 43.79 " ERROR BOX CORNER 1: 13 h 50 m 25.94 s 62 o 13 ' 54.09 " ERROR BOX CORNER 2: 13 h 50 m 25.32 s 61 o 29 ' 58.72 " ERROR BOX CORNER 3: 13 h 49 m 57.94 s 62 o 10 ' 25.39 " ERROR BOX CORNER 4: 13 h 49 m 57.26 s 61 o 25 ' 42.46 " OR ERROR BOX CENTER: 13 h 44 m 44.28 s 54 o 40 ' 41.39 " ERROR BOX CORNER 5: 13 h 44 m 23.07 s 54 o 17 ' 40.27 " ERROR BOX CORNER 6: 13 h 45 m 23.41 s 55 o 00 ' 43.10 " ERROR BOX CORNER 7: 13 h 44 m 05.82 s 54 o 21 ' 43.49 " ERROR BOX CORNER 8: 13 h 45 m 06.47 s 55 o 05 ' 34.50 " These error boxes may be improved considerably, and we are seeking auxiliary data which may allow us to distinguish between these two possibilities. Maps will be posted shortly at sunspot.ssl.berkeley.edu/ipn3/020715.
