TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1548 SUBJECT: Improved IPN position for GRB020918 (two large error boxes) DATE: 02/09/20 20:43:59 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses GRB team, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, and T. Cline, on behalf of the Ulysses and Konus-Wind GRB teams, report: A preliminary analysis of the Konus data for this event (GCN 1546) indicates that it originated from an ecliptic latitude between +20 and +40 degrees. Combining this information with the triangulated position (an annulus centered at RA, Decl (2000)=171.715, 38.791 degrees, whose 3 sigma radius is 88.681 +/-0.030 degrees) limits the possible arrival directions to the two sections of the annulus contained between RA, Decl (2000)= 14.4, 50.3 and 45.4, 38.0 degrees, and between RA, Decl (2000)= 257.7, -2.9 and 273.8, 16.6 degrees.
