TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  1376
SUBJECT: IPN triangulation of GRB020418

FROM:    Kevin Hurley at UCBerkeley/SSL  <khurley@sunspot.ssl.berkeley.edu>

K. Hurley, on behalf of the Ulysses GRB team;

F. Frontera, C. Guidorzi, and E. Montanari, on behalf of the BeppoSAX GRBM team;

I. Mitrofanov, D. Anfimov, A. Kozyrev, M. Litvak, and A. Sanin,
on behalf of the HEND/Odyssey GRB team;

T. Cline, on behalf of the Ulysses and Mars Odyssey GRB teams; 

W. Boynton, C. Fellows, K. Harshman, C. Shinohara, and R. Starr, on
behalf of the GRS/Odyssey GRB team, report:

Ulysses, Mars Odyssey - HEND, and BeppoSAX observed this
GRB at 31110 s.  As observed by Ulysses, it had a duration of ~15
seconds, a 25-100 keV fluence of ~10^-5 erg/cm2, and a peak flux of
~10^-6 erg/cm2 s over 0.25 s.

We have triangulated it to a preliminary, 3 sigma error box
with approximate area 20 square arcminutes whose coordinates
are:

                     RA(2000)                 DEC(2000)
 ERROR BOX CENTER:  08 h 00 m 17.58 s    -48 o 38 '  43.64 " 
 ERROR BOX CORNER 1: 08 h 00 m 43.70 s    -48 o 38 '  11.00 " 
 ERROR BOX CORNER 2: 07 h 59 m 43.77 s    -48 o 36 '  59.65 " 
 ERROR BOX CORNER 3: 08 h 00 m 51.42 s    -48 o 40 '  27.43 " 
 ERROR BOX CORNER 4: 07 h 59 m 51.46 s    -48 o 39 '  16.15 " 



This error box can be improved.
