Fletcher (USRA) reports on behalf of the Fermi-GBM team:\nFor the IceCube high-energy neutrino candidate event IceCube-200425A\n(GCN 27651), at the event time Fermi-GBM was observing the reported\nneutrino location at:\n\nRA: 100.10 (+4.67/-3.14 deg  90% PSF containment) J2000\nDec: 53.57 (+2.45/-1.60 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 identified\na low reliability event 8.93 minutes before IceCube-200425A\n(https://gcn.gsfc.nasa.gov/notices_gbm_sub/609549478.fermi). However\ndue to the temporal offset and low reliability, we do not consider these\ntwo events associated.\n\nThe GBM targeted search, the most sensitive, coherent search for GRB-like\nsignals, was run from +/-30 s around the neutrino candidate time.\nFrom this search, no significant signal was found related\nto IceCube-200425A.\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:    7.3      14.      37.\n1.024 s:    2.6      3.9      10.\n8.192 s:    0.8      1.8      3.5\n\nThese results are preliminary.",
