Wood (NASA/MSFC) reports on behalf of the Fermi-GBM team:\n\nFor the IceCube high-energy neutrino candidate event IceCube-200929A\n(GCN 28532), at the event time Fermi-GBM was observing the reported\nneutrino location at:\n\nRA: 29.53 (+0.53 -0.53 deg 90% PSF containment) J2000\nDec: 3.47 (+0.71 -0.35 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\nbursts below the onboard triggering threshold in Fermi-GBM also\nidentified no counterpart candidates. The GBM targeted search,\nthe most sensitive, coherent search for GRB-like signals,\nwas run from +/-30 s around the neutrino candidate time.\nFrom this search, no significant signal was found related\nto IceCube-200929A.\n\nWe set upper limits on impulsive gamma-ray emission. Using the\nrepresentative soft, normal, and hard GRB-like templates described in\narXiv:1612.02395, we set the following 3 sigma flux upper limits over\n10-1000 keV (in units of 10^-7 erg/s/cm^2):\n\nTimescale   Soft     Normal   Hard\n-------------------------------------------\n0.128 s:    5.6      9.7      16.\n1.024 s:    2.2      3.7      7.0\n8.192 s:    0.8      1.3      2.1\n\nThese results are preliminary.",
