GRB000419
From: GCN Circulars gcncirc@lheawww.gsfc.nasa.gov To: OERLICON@intelos.net Subject: Correction to IPN error box for GRB000419 Date: Friday, April 21, 2000 6:50 PM
TITLE: GCN GRB OBSERVATION REPORT NUMBER: 643 SUBJECT: Correction to IPN error box for GRB000419 DATE: 00/04/21 22:39:48 GMT FROM: Kevin Hurley at UCBerkeley/SSL khurley@sunspot.ssl.berkeley.edu
K. Hurley, on behalf of the IPN GRB teams, and R. M. Kippen, on behalf of the BATSE GRB team, report:
This burst was initially localized to two alternate error boxes by the IPN. One of the error boxes was eliminated with >95% confidence by the directional responses of some of the IPN detectors. However, the error box given in GCN 641 was unocculted to BATSE at the time of the burst, and definitely should have been detected by it, but was not. As the alternate position was occulted to BATSE, we now believe it to be the correct one. It is a 220 sq. arcmin. error box, given by the following preliminary coordinates:
RA(2000) DEC(2000) 22 h 0 m 15.79 s 48 o 16 ' 53.54 " (CENTER) 22 h 1 m 36.22 s 48 o 14 ' 32.33 " (CORNER) 22 h 2 m 6.22 s 48 o 5 ' 27.93 " (CORNER) 21 h 58 m 21.44 s 48 o 28 ' 24.10 " (CORNER) 21 h 58 m 54.62 s 48 o 19 ' 13.33 " (CORNER)
The other parameters for the burst given in GCN 641 are unchanged.
KH apologizes for any inconvenience caused.

TITLE: GCN GRB OBSERVATION REPORT NUMBER: 641 SUBJECT: GRB000419 DATE: 00/04/20 16:34:45 GMT FROM: Kevin Hurley at UCBerkeley/SSL khurley@sunspot.ssl.berkeley.edu
K. Hurley, on behalf of the Ulysses GRB Team, M. Feroci, F. Frontera, and C. Guidorzi, on behalf of the BeppoSAX GRBM team, T. Cline and E. Mazets, on behalf of the NEAR and KONUS-Wind teams, report:
Ulysses, SAX, KONUS, and NEAR detected GRB000419 at 07970 s UT. As observed by Ulysses, this burst had a duration of 40 s and a 25-100 keV fluence of 4.3 x 10^-6 erg/cm^2. We have triangulated it to a 220 sq. arcmin. error box whose preliminary 3 sigma coordinates are:
RA(2000) DEC(2000) 19 h 43 m 7.13 s 51 o 35 ' 18.53 " (CENTER) 19 h 41 m 40.18 s 51 o 36 ' 51.54 " (CORNER) 19 h 40 m 52.76 s 51 o 29 ' 34.62 " (CORNER) 19 h 45 m 25.59 s 51 o 40 ' 55.14 " (CORNER) 19 h 44 m 34.68 s 51 o 33 ' 41.76 " (CORNER)
This error box can be refined.
