TITLE: GCN CIRCULAR NUMBER: 15672 SUBJECT: GRB 131231A: Fermi GBM correction to GCN 15644 DATE: 14/01/03 19:03:04 GMT FROM: Peter Jenke at MSFC P. Jenke (UAH) reports on behalf of the Fermi GBM team: "The quoted fluence (10-1000 keV) in GCN 15644 (P. Jenke et al) was in fact the time integrated average energy flux for this burst. The actual fluence (10-1000 kev) for this event is (1.400 +/- 0.001)E-4 ergs/cm^2."
