TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2278 SUBJECT: IPN triangulation of GRB030607 (annulus) DATE: 03/06/09 22:12:51 GMT FROM: Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu> K. Hurley, on behalf of the Ulysses GRB team, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, T. Cline, on behalf of the Ulysses and Konus GRB teams, and A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, report: Konus and INTEGRAL (SPI-ACS) observed this event at 08362 s. Its duration was approximately 0.15 s. We have triangulated it to a preliminary annulus centered at RA, Decl (2000)= 57.940, +19.247 degrees, with radius 36.337 +/- 1.892 degrees (3 sigma). As this annulus does not include any of the known SGRs, this event is probably a short/hard GRB. This annulus may be constrained and/or improved, but as this burst was not observed by Ulysses or Mars Odyssey, a small error box cannot be obtained for it.
