TITLE:   GCN CIRCULAR
NUMBER:  7790
SUBJECT: GRB 080603: A long GRB detected by INTEGRAL
DATE:    08/06/03 13:04:48 GMT
FROM:    Sandro Mereghetti at IASF/CNR  <sandro at iasf-milano.inaf.it>

A.Paizis, S.Mereghetti (IASF-Milano), D.Gotz (CEA-Saclay), M. Turler, 
V.Beckmann, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on 
behalf of the IBAS Localization Team report:

A GRB lasting about 180 s has been detected by IBAS in IBIS/ISGRI data at 
11:18:11 UT of June 3. The coordinates (J2000)  are:

 RA:  279.409 [degrees]
 DEC: +62.735 [degrees]

with an uncertainty of 2 arcmin (90% c.l.).

A preliminary analysis gives a peak flux in the 20-200 keV range of about 
0.5 ph/cmq/s (1-s integration time) and a fluence over the same energy 
range of about 10e-6 erg/cmq.

A plot of the light curve will be posted at
