A high-energy neutrino event detected by IceCube on 22 September 2017 was coincident in direction and time with a gamma-ray flare from the blazar TXS 0506+056. Prompted this association, we investigated 9.5 years of observations to search for excess emission at position blazar. We found an events, respect atmospheric backgrounds, that between 2014 March 2015. Allowing time-variable flux, constitutes 3.5σ evidence 0506+056, independent prior flaring episode. This suggests blazars are identifiable sources astrophysical flux.
