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-190104A (GCN 23605). The
closest onboard trigger occurred approximately 16 hours after the
neutrino event time and was identified as a terrestrial gamma-ray
flash unassociated with the neutrino. The ground-based untargeted
search of GBM data did not find any significant candidates within
+/- 1 hour of the event time. The targeted search ([1],[2]) was also
run +/- 30 s around the event time, and no significant candidates
were found. Upper limits on persistent emission using the Earth
Occultation technique [3] will be forthcoming.���
