TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1772 SUBJECT: IPN triangulation of GRB021219 - CORRECTION DATE: 02/12/19 22:46:36 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley and T. Cline, on behalf of the Ulysses GRB team, and D.Gotz (IASF-Milano), P.Favre (ISDC), S. Mereghetti (IASF-Milano), J. Borkowski (ISDC), and the INTEGRAL Science Working team, report: The IPN annulus actually intersects the INTEGRAL error circle given in GCN 1768 at four points, not two: RA DEC 282.572616=18 h 50 m 17 s 31.849899= 31 o 50 ' 59 " 282.664692=18 h 50 m 39 s 31.957916= 31 o 57 ' 28 " 282.546093=18 h 50 m 11 s 31.898856= 31 o 53 ' 55 " 282.601577=18 h 50 m 24 s 31.963983= 31 o 57 ' 50 " Thus the agreement between the annulus and the error circle is improved, but the error box size increases to about 22 square arcminutes.
