GCN Circular 270
K. Hurley (UC Berkeley Space Sciences Laboratory) on behalf of the Ulysses GRB team, and M. Feroci (IAS - Rome) on behalf of the BeppoSAX GRB Team, report: A refined IPN annulus for GRB981220 has been obtained by triangulation between Ulysses and BeppoSAX. It is centered at RA(2000)=347.398 degrees, Delta(2000)=+07.340 degrees, with radius 67.118 degrees, and 3 sigma half-width 0.015 degrees. The radio source reported by Frail et al. (GCN 170) and by Galama et al. (GCN 168) lies 0.027 degrees from the center line of the annulus, and is therefore outside it. Further refinement in the annulus half-width is possible, but we can state with some certainty that the position of the radio source is incompatible with that of the gamma-ray burst.
