TITLE: GCN CIRCULAR NUMBER: 26260 SUBJECT: IceCube-191119A: Upper limits from Fermi-GBM Observations DATE: 19/11/19 17:58:03 GMT FROM: Cori Fletcher at USRA C. Fletcher (USRA) reports on behalf of the Fermi-GBM Team: For the IceCube high-energy neutrino candidate event 191119A (GCN 26258), at the event time Fermi-GBM was observing the reported neutrino location at: RA: 230.10 (+4.76/-6.48 deg 90% PSF containment) J2000 Dec: 3.17 (+3.36/-2.09 deg 90% PSF containment) J2000 There was no Fermi-GBM onboard trigger around the event time of the neutrino candidate. An automated, blind search for short gamma-ray bursts below the onboard triggering threshold in Fermi-GBM also identified no counterpart candidates. The GBM targeted search, the most sensitive, coherent search for GRB-like signals, was run from +/-30 s around the neutrino candidate time. From this search, no significant signal was found related to IceCube-191119A. We set upper limits on impulsive gamma-ray emission. Using the representative soft, normal, and hard GRB-like templates (arXiv:1612.02395), we report the following 3 sigma flux upper limits over 10-1000 keV (in units of 10^-7 erg/s/cm^2): Timescale soft norm hard -------------------------------------- 0.128 s: 5.0 8.4 22.0 1.024 s: 1.3 2.2 5.4 8.192 s: 0.6 1.1 2.9
