TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2274 SUBJECT: IPN triangulation of GRB030605B (annulus) DATE: 03/06/06 23:32:50 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses team, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, and A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, report: Ulysses, Konus-Wind, and INTEGRAL (SPI-ACS) observed this GRB at 75986 seconds. As observed by Ulysses, it had a duration of approximately 5 seconds, a 25-100 keV fluence of approximately 5.2E-06 erg/cm2, and a peak flux of approximately 5.0E-07 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 152.163, 32.665 degrees, whose radius is 30.786 +/- 0.099 degrees (3 sigma). This annulus can be constrained and/or improved, but as the event was not observed by Mars Odyssey, a small error box cannot be derived for it.
