TITLE: GCN CIRCULAR NUMBER: 23346 SUBJECT: Fermi GBM Observation of IceCube-181014A DATE: 18/10/17 20:37:56 GMT FROM: C. Michelle Hui at MSFC/Fermi-GBM B. Mailyan (UAH), P. Veres (UAH), P. Jenke (UAH), A. Goldstein (USRA), and C. M. Hui (MSFC) report on behalf of the Fermi GBM team: We have searched the Fermi Gamma-ray Burst Monitor data for a gamma-ray counterpart to IceCube-181014A (GCN 23338). The position was occulted by the Earth for Fermi at the time the neutrino was detected. GBM therefore cannot set any limits on impulsive emission. The ground-based untargeted search of GBM data did not find any candidates within +/- 1 hour of the event time. Measurements using the Earth Occultation technique around this position place a three sigma flux upper limit of about 190 mCrab for 12-100 keV between Oct 13th and Oct 15th.
