  Spectral and anisotropy properties of IceCube astrophysical neutrino signal
reveal an evidence for a significant Galactic contribution to the neutrino flux
in Southern hemisphere. We check if the Galactic contribution is detectable in
the astrophysical muon neutrino flux observed from a low positive declinations
region of the Northern sky. Estimating the Galactic neutrino flux in this part
of the sky from gamma-ray and Southern sky neutrino data, we find that the
Northern sky astrophysical muon neutrino signal shows an excess over the
Galactic flux. This points to the presence of an additional hard spectrum
(extragalactic or large scale Galactic halo) component of astrophysical
neutrino flux. We show that the Galactic flux component should still be
detectable in the muon neutrino data in a decade long IceCube exposure.
