TITLE: GCN GRB OBSERVATION REPORT NUMBER: 626 SUBJECT: GRB000408 [IPN Position] DATE: 00/04/08 21:43:25 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, S. Barthelmy, R. M. Kippen, and T. Cline, on behalf of the Ulysses, BATSE, and NEAR GRB teams, report: Ulysses, BATSE, and NEAR observed GRB000408 (=BATSE 8069) at 9348 s UT. As observed by Ulysses, this burst had a T90 duration of 2.5 s, a 25-100 keV fluence of 7.4x10^-6 erg/cm^2, and a peak flux over 0.5 s of 3.7x10^-6 erg/cm^2 s. Preliminary triangulation gives a ~200 sq. arcmin. error box with the following coordinates: RA(2000) DEC(2000) 9 h 10 m 31.86 s 66 o 34 ' 35.72 " (CENTER) 9 h 14 m 57.83 s 66 o 30 ' 25.93 " (CORNER) 9 h 7 m 41.72 s 66 o 33 ' 18.90 " (CORNER) 9 h 13 m 19.82 s 66 o 35 ' 43.51 " (CORNER) 9 h 5 m 56.89 s 66 o 38 ' 22.95 " (CORNER) It should be possible to refine this error box considerably within 24 h, when the high time resolution data become available.
