TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2165 SUBJECT: IPN triangulation of GRB030422B (annulus) DATE: 03/04/24 16:30:36 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley and T. Cline, on behalf of the Ulysses and Konus GRB teams, D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wigger, W. Hajdas, and A. Zehnder, on behalf of the RHESSI GRB 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, RHESSI, Konus-Wind, and INTEGRAL (SPI-ACS) observed this GRB at 32487 seconds. As observed by Ulysses, it had a duration of approximately 15 seconds, a 25-100 keV fluence of approximately 8.8E-05 erg/cm2, and a peak flux of approximately 1.3E-06 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 333.705, -38.663 degrees, whose radius is 69.139 +/- 0.118 degrees (3 sigma ). This annulus may be constrained and/or improved, but it is not known at this point whether this event was observed by Mars Odyssey, and thus whether a small error box can be derived for it.
