TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1719 SUBJECT: IPN triangulation of GRB021201 (short/hard burst, small error box) DATE: 02/12/03 01:15:58 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley and T. Cline, on behalf of the Ulysses, HETE, Mars Odyssey, and KONUS 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, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, G. Ricker, J-L Atteia, N.

Boer, J-F Olive, and J-P Dezalay, on behalf of the HETE GRB team, and D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wigger, W. Hajdas, and A. Zehnder, on behalf of the RHESSI GRB team, report: Ulysses, Mars Odyssey-HEND, RHESSI, HETE-FREGATE, and Konus-Wind observed this GRB at 19804 seconds. As observed by Ulysses, it had a duration of approximately 0.3 seconds, a 25-100 keV fluence of approximately 2E-07 erg/cm2, and a peak flux of approximately 8E-07 erg/cm2 s over 0.25 seconds. We have triangulated it a preliminary, 3 sigma error boxes with approximate area 9 square arcminutes whose coordinates are: RA(2000) DEC(2000) ERROR BOX CENTER: 8 h 7 m 46.09 s 21 o 14 ' 17.73 " (CENTER) ERROR BOX CORNER 1: 8 h 7 m 45.73 s 21 o 12 ' 40.07 " (CORNER) ERROR BOX CORNER 2: 8 h 7 m 56.62 s 21 o 11 ' 40.15 " (CORNER) ERROR BOX CORNER 3: 8 h 7 m 35.56 s 21 o 16 ' 55.47 " (CORNER) ERROR BOX CORNER 4: 8 h 7 m 46.46 s 21 o 15 ' 55.39 " (CORNER) A Chandra NRA-accepted target of opportunity observation of this error box is being requested. This error box may be improved slightly.
