TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2206 SUBJECT: IPN triangulation of GRB030505B (large error box) DATE: 03/05/06 16:50:53 GMT FROM: Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu> 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 32605 seconds. As observed by Ulysses, it had a duration of approximately 105 seconds, a 25-100 keV fluence of approximately 5.2E-06 erg/cm2, and a peak flux of approximately 8.4E-07 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 152.354, 36.983 degrees, whose radius is 66.151 +/- 0.034 degrees (3 sigma ). In addition, the Konus ecliptic latitude response limits the arrival direction to ecliptic latitudes between -48 and -32 degrees, that is, to that portion of the annulus between RA, Decl = 101.6, -9.1 degrees and 164.0, -28.2 degrees. This annulus may be further constrained and/or improved, but as the event was not observed by Mars Odyssey, a small error box cannot be derived for it.
