TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  2397
SUBJECT: GRB030922 triangulation (annulus)
DATE:    03/09/23 10:21:51 GMT
FROM:    Dmitry Frederiks at Ioffe Institute  <fred@mail.ioffe.ru>

S. Golenetskii, E. Mazets, V. Pal'shin, and D. Frederiks on behalf
of Konus-Wind and Helicon/Coronas-F teams,

T. Cline, on behalf of the Konus GRB team, peport:

GRB030922 was detected by Konus-Wind at 08:43:24.120 UT
and Helicon-Coronas-F at 08:43:22.193 UT. It has a duration of ~35 sec.
There was a possible weak precursor 190 sec before trigger time, it had 
been detected by both instruments.

We have triangulated it to a preliminary annulus centered at
RA(2000) = 262.610 deg,
Decl(2000) = -18.591 deg,
Radius = 54.9 +/- 3.0 degrees (3 sigma ).
