TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2205 SUBJECT: IPN triangulation of GRB030505A (annulus) DATE: 03/05/06 16:28:33 GMT FROM: Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu> K. Hurley and T. Cline, on behalf of the Ulysses GRB team, and A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, report: Ulysses and INTEGRAL (SPI-ACS) observed this burst at 27539 s. As observed by Ulysses, it had a duration of approximately 40 seconds, a 25-100 keV fluence of approximately 2.2E-06 erg/cm2, and a peak flux of approximately 4.9E-07 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 152.204, 37.050 degrees, whose radius is 77.910 +/- 0.133 degrees (3 sigma ). This annulus may be constrained and/or improved, but as the event was not observed by Mars Odyssey, a small error box cannot be derived for it.
