TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  641
SUBJECT: GRB000419 [IPN Position]
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.

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.
