TITLE: GCN CIRCULAR
NUMBER: 39298
SUBJECT: GRB 250211B: A long GRB detected by INTEGRAL
DATE: 25/02/12 07:26:35 GMT
FROM: Sandro Mereghetti at IASF-Milano/INAF
S.Mereghetti (INAF, IASF-Milano), D.Gotz (CEA, Saclay), C.Ferrigno, E.Bozzo, V.Savchenko (ISDC, Versoix), L.Ducci (IAAT, Germany and ISDC, Versoix) and J.Borkowski (CAMK, Torun) report:
a gamma ray burst lasting about 60 s has been detected by IBAS in the IBIS/ISGRI data at 21:27:10 UT of 2025 February 11.
The refined coordinates (J2000) are:
R.A.= 276.3784 deg
DEC.= -31.9655 deg
with an uncertainty of 2 arcmin (90% c.l.).
The burst had a peak flux of about 0.2 ph/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 4e-7 erg/cmq.
A plot of the light curve will be posted at
