GCN Circular 160
K. Hurley (UC Berkeley), on behalf of the Ulysses/GRB team, T. Cline (NASA-GSFC), E. Mazets, and S. Golenetskii (Ioffe Physico-Technical Institute), on behalf of the KONUS-Wind team, and D. A. Smith (MIT) report: "Ulysses and KONUS detected GRB981220. A preliminary triangulation annulus for this event is centered at RA(2000)=347.373 degrees, Decl(2000)=+7.336 degrees, with a radius 67.134 +/- 0.020 degrees (3 sigma). This annulus intersects the RXTE/ASM error box at RA(2000) Decl(2000) 3h 42m 28.5s 17o 06.3' 3h 42m 29.0s 17o 11.1' 3h 42m 39.0s 17o 11.6' 3h 42m 38.5s 17o 06.8' to form a ~2.4' x 4.5' error box with approximately 11 sq. arcmin. area. The IPN annulus width can be reduced by a factor of 2 to 4. An image may be found at http://ssl.berkeley.edu/ipn3/newdata.html, under 981220." This message is quotable in publications.
