Burns (NASA/GSFC) reports on behalf of the Fermi-GBM Team:\n\nFor the IceCube high-energy neutrino candidate event 190922B (GCN 25806),\nat the event time Fermi-GBM was observing the reported neutrino location at:\n\nRA: 5.76 (+ 1.19 - 1.37 deg  90% PSF containment) J2000\nDec: -1.57(+ 0.93 - 0.82 deg 90% PSF containment) J2000\n\nThere was no Fermi-GBM onboard trigger around the event time of the\nneutrino candidate. An automated, blind search for short gamma-ray bursts\nbelow the onboard triggering threshold in Fermi-GBM also identified no\ncounterpart candidates. The GBM targeted search, the most sensitive,\ncoherent search for GRB-like signals, was run from +/-30 s around the\nneutrino candidate time. From this search, no significant signal was found\nrelated to IceCube-190922B.\n\nWe set upper limits on impulsive gamma-ray emission. Using the\nrepresentative soft, normal, and hard GRB-like templates\n(arXiv:1612.02395), we report the following 3 sigma flux upper limits over\n10-1000 keV (in units of 10^-7 erg/s/cm^2):\n\nTimescale  soft     norm     hard\n--------------------------------------\n0.128 s:   2.9      5.2      11.\n1.024 s:   0.8      1.5      2.7\n8.192 s:   0.3      0.6      1.1",
