TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2332 SUBJECT: IPN triangulation of GRB030722 (large error box) DATE: 03/07/28 18:38:28 GMT FROM: Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu> K. Hurley and T. Cline, on behalf of the Ulysses and Konus-Wind GRB teams, 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 48701 seconds. As observed by Ulysses, it had a duration of approximately 30 seconds, a 25-100 keV fluence of approximately 2.0E-05 erg/cm2, and a peak flux of approximately 3.4E-06 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 156.737, 26.594 degrees, whose radius is 64.285 +/- 0.014 degrees (3 sigma). In addition, the Konus ecliptic latitude response limits the arrival direction to ecliptic latitudes between -36 and -40 degrees, that is, to those portions of the annulus between approximately RA, Decl=104.9, -13.5 degrees and 109.2, -18.1 degrees. 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.
