M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf of the
IBAS Localization Team report:
A GRB lasting about 80 s has been detected by IBAS in IBIS/ISGRI
data at 22:05:44 on December 11 2005.
Its refined coordinates (J2000) are:
RA: 345.688 [degrees]
DEC: 55.079 [degrees]
with an uncertainty of 2.0 arcmin (90% c.l. radius).
Its preliminary peak flux (20-200 keV, 1s integration time) is about 0.8
ph (8x10e-8 erg)/cmsq/s. Its fluence (20-200 keV, 80 s integration time)
is 2x10e-6 erg/cmsq.
A plot of the light curve will be posted at
