TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2277 SUBJECT: IPN triangulation of GRB030606 (two alternate error boxes) DATE: 03/06/09 21:07:47 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley and T. Cline, on behalf of the Ulysses, Konus, and Mars Odyssey GRB teams, A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS 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 E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, report: Ulysses, INTEGRAL (SPI-ACS), Mars Odyssey (HEND and GRS), and Konus-Wind observed this GRB at 85670 seconds. As observed by Ulysses, it had a duration of approximately 10 seconds, a 25-100 keV fluence of approximately 1.5E-06 erg/cm2, and a peak flux of approximately 9.7E-07 erg/cm2 s over 0.25 seconds. We have triangulated it to two alternate, preliminary, 3 sigma error boxes each with approximate area 1020 square arcminutes, whose coordinates are: RA(2000) DEC(2000) ERROR BOX CENTER: 12 h 6 m 29.49 s -36 o 17 ' 27.67 " ERROR BOX CORNER 1: 12 h 7 m 17.26 s -36 o 14 ' 49.41 " ERROR BOX CORNER 2: 11 h 53 m 34.30 s -37 o 28 ' 50.84 " ERROR BOX CORNER 3: 12 h 18 m 10.77 s -35 o 3 ' 43.37 " ERROR BOX CORNER 4: 12 h 5 m 41.49 s -36 o 20 ' 5.16 " OR ERROR BOX CENTER: 6 h 28 m 35.36 s -19 o 38 ' 41.14 " ERROR BOX CORNER 5: 6 h 28 m 0.96 s -19 o 32 ' 51.16 " ERROR BOX CORNER 6: 6 h 37 m 4.07 s -21 o 40 ' 59.82 " ERROR BOX CORNER 7: 6 h 20 m 56.12 s -17 o 40 ' 50.73 " ERROR BOX CORNER 8: 6 h 29 m 9.93 s -19 o 44 ' 31.80 " There is a chance that the ambiguity can be resolved by further processing. These error boxes may be improved.
