TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1869 SUBJECT: IPN triangulation of GRB030216 (annulus) DATE: 03/02/17 21:14:30 GMT FROM: Kevin Hurley at UCBerkeley/SSL 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 58424 s. As observed by Ulysses, it had a duration of approximately 3 seconds, a 25-100 keV fluence of approximately 2.4E-06 erg/cm2, and a peak flux of approximately 3.4E-07 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 171.796, +41.728 degrees, whose radius is 50.029 +/- 0.127 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.
