behalf of the IBAS Localization Team, S. Shaw and R. Walter on behalf of
the INTEGRAL Science data Centre (ISDC) and the INTEGRAL Science Working
Team report:
An 8 s long GRB has been detected with the INTEGRAL Burst Alert System
(IBAS) on April 22 at 06:58:02 UT. The GRB has been detected with
IBIS/ISGRI in the 15-200 keV band. Its coordinates (J2000) are:
R.A. 18h 42m 00s
Dec. +01deg 59' 29''
with an uncertainty of 2.5 arcmin.
The preliminary peak flux in the 20-200 keV range is about 2.7
photons/cmsq/s (2.5 x 10^-7 erg/cmsq/s) (1 s integration time).
