D. Gotz (CEA Saclay), S. Mereghetti (IASF-Milano), E. Bozzo, C. Ferrigno, R. Farinelli, (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf of the  IBAS Localization Team report:

a gamma ray burst lasting about 6 s has been detected by IBAS in the IBIS/ISGRI data at  21:05:32 U.T. on December 18.
Its refined  coordinates (J2000)  are:

  R.A.: 113.7807 deg
  DEC.: -64.7373 deg

with an uncertainty of 1.8 arc min (90% c.l.).

A preliminary estimation of the burst fluence is 5x10^-7 erg/cmsq in the 20-200 keV energy band.

A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html
