[vsnet-grb-info 814] IPN triangulation of GRB030320



TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  1942
SUBJECT: IPN triangulation of GRB030320
DATE:    03/03/20 17:42:36 GMT
FROM:    Kevin Hurley at UCBerkeley/SSL  <khurley@sunspot.ssl.berkeley.edu>

K. Hurley and T. Cline, on behalf of the Ulysses, Mars Odyssey,
and KONUS GRB teams,

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

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

E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, and

A. von Kienlin, G. Lichti, and A. Rau, on behalf of the
INTEGRAL SPI-ACS GRB team, report:

Konus, Mars Odyssey (HEND), and INTEGRAL (SPI-ACS) observed this
event (GCN 1941).  We confirm that this is indeed a gamma-ray
burst.  Because the burst arrived along a direction close
to the Konus-Mars vector, the triangulation annulus is imprecise.
It is centered at RA, Decl = 280.256, -23.488 degrees, and
has a radius 11.122 +/- 0.456 degrees.  This annulus is consistent
with, but does not constrain, the IBIS localization in GCN 1941.
Ulysses data are expected within 24 hours, and may improve this
triangulation.
