TITLE: GCN CIRCULAR NUMBER: 19758 SUBJECT: GBM Observations of IceCube 160731 DATE: 16/08/02 22:51:16 GMT FROM: Eric Burns at U of Alabama E. Burns (UAH) and P. Jenke (UAH) report on behalf of the GBM Team: At 01:55:04 UTC on July 31 2016 the IceCube collaboration observed an event that has a high probability of being an astrophysical neutrino at RA 215.1090, Dec -0.4581 (J2000) (AMON ICECUBE HESE 128290 6888376). This position was occulted by the Earth for Fermi at the time the neutrino was detected. GBM therefore cannot set any limits on impulsive emission. Measurements using the Earth Occultation technique around this position place a three sigma flux upper limit of about 230 mCrab between 12 and 100 keV between July 30th and August 1st.
