//////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 512 SUBJECT: IPN error boxes for GRB991229 DATE: 99/12/30 22:50:51 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses GRB team, and T. Cline and E. Mazets, on behalf of the KONUS-WIND and NEAR GRB teams, report: Ulysses, KONUS-WIND, and NEAR observed a moderately intense (25-100 keV fluence ~10^-5 erg/cm^2), 100 s long gamma-ray burst on December 29, 1999 at 15:10:26 UT. Triangulation of this event yields two alternate, ~700 sq. arcmin. error boxes whose corners are at: RA(2000) DEC(2000) 22 h 26 m 7.91 s 28 o 43 ' 45.47 " 22 h 24 m 41.17 s 29 o 10 ' 38.02 " 22 h 25 m 45.15 s 29 o 28 ' 9.61 " 22 h 24 m 5.15 s 30 o 4 ' 45.86 " AND 22 h 17 m 11.91 s 35 o 22 ' 46.66 " 22 h 17 m 2.57 s 34 o 49 ' 56.05 " 22 h 18 m 45.26 s 34 o 42 ' 23.34 " 22 h 18 m 49.07 s 33 o 59 ' 50.67 " Although these error boxes can be refined, it will probably not be possible to resolve the ambiguity between them with the present observations. //////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 516 SUBJECT: Single IPN error box for GRB991229 DATE: 00/01/05 18:35:47 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses GRB team, C. Kouveliotou and R. M. Kippen, on behalf of the BATSE GRB team, and T. Cline and E. Mazets, on behalf of the KONUS-WIND and NEAR GRB teams, report: GRB991229 (GCN 512) was observed by BATSE (trigger 7925). The BATSE localization indicates that the second error box given in GCN 512 is the correct one: RA(2000) DEC(2000) 22 h 17 m 11.91 s 35 o 22 ' 46.66 " 22 h 17 m 2.57 s 34 o 49 ' 56.05 " 22 h 18 m 45.26 s 34 o 42 ' 23.34 " 22 h 18 m 49.07 s 33 o 59 ' 50.67 "
