• GCN Circular #22946
  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 30 s has been detected by IBAS in the IBIS/ISGRI data at 13:01:15 UT of 2018 July 14.
  The refined coordinates (J2000) are:

  R.A.= 242.9191 deg
  DEC.= 33.2811  deg
  

  with an uncertainty of 2.5 arcmin (90% c.l.).
  The burst had a peak flux of 0.3 counts/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 3x10^-7 erg/cmq.
  A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html
