TITLE: GCN CIRCULAR NUMBER: 1450 SUBJECT: IPN triangulation of GRB020708 DATE: 02/07/08 23:19:56 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses GRB team, T. Cline, on behalf of the Ulysses and Konus-Wind GRB teams, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, 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, report: Ulysses, Konus, and Mars Odyssey-HEND observed this burst at 16451 s. As observed by Ulysses, it had a duration of about 150 seconds, a 25-100 keV fluence of approximately 1.4E-05 erg/cm2, and a peak flux of approximately 1.0E-06 erg/cm2 s over 0.25 seconds. We have triangulated it to two alternate, preliminary, 3 sigma error boxes each with approximate area 110. square arcminutes whose coordinates are: RA(2000) DEC(2000) ERROR BOX CENTER: 9 h 16 m 19.46 s 28 o 26 ' 37.60 " ERROR BOX CORNER 1: 9 h 16 m 13.03 s 28 o 23 ' 22.43 " ERROR BOX CORNER 2: 9 h 16 m 25.91 s 28 o 29 ' 52.73 " ERROR BOX CORNER 3: 9 h 16 m 56.59 s 28 o 19 ' 23.24 " ERROR BOX CORNER 4: 9 h 15 m 41.80 s 28 o 33 ' 58.02 " ERROR BOX CORNER 5: 9 h 15 m 49.64 s 28 o 27 ' 31.01 " ERROR BOX CORNER 6: 9 h 16 m 49.24 s 28 o 25 ' 44.61 " OR ERROR BOX CENTER: 7 h 58 m 5.36 s 41 o 35 ' 38.95 " ERROR BOX CORNER 7: 7 h 57 m 49.90 s 41 o 33 ' 35.55 " ERROR BOX CORNER 8: 7 h 58 m 20.82 s 41 o 37 ' 42.25 " ERROR BOX CORNER 9: 7 h 57 m 18.40 s 41 o 42 ' 08.53 " ERROR BOX CORNER 10: 7 h 58 m 52.84 s 41 o 29 ' 03.72 " ERROR BOX CORNER 11: 7 h 58 m 17.24 s 41 o 29 ' 25.08 " ERROR BOX CORNER 12: 7 h 57 m 53.51 s 41 o 41 ' 52.39 " There is a chance that the ambiguity can be resolved by further processing. These error boxes may be improved. A map will be posted shortly at ssl.berkeley.edu/ipn3/020708. Note that somewhat larger, four-sided error boxes were circulated in the GCN socket message, for reasons related to the formatting of those messages. The above, smaller error boxes are the more precise ones.
