S.Mereghetti, D. Gotz, (IASF, Milano), S.Shaw, M. Beck, A. Paizis
(ISDC, Versoix), J.Borkowski (CAMK, Torun) on behalf of the IBAS
Localization Team report:

A 60 s long GRB has been detected with the INTEGRAL Burst Alert System
(IBAS) on December 18 at 15:45:25 UT. The GRB has been detected with
IBIS/ISGRI in the 15-200 keV band (IBAS Alert # 2072).

Its coordinates (J2000)  are:

R.A.: 24.7731 [degrees],
DEC.: 71.3346 [degrees]

with an uncertainty of 2.5 arcmin  (90% c.l. radius)

The preliminary peak flux in the 20-200 keV range is about 3
photons/cmsq/s (1.6E-7 erg/cmsq/s) (1 s integration time).
