A first-ever 2-dimensional celestial map of primary cosmic-ray flux was obtained from 2:10 10 8 cosmic-ray muons accumulated in 1662.0 days of Super-Kamiokande. The celestial map indicates an (0:104 0:020)% excess region in the constellation of Taurus and a (0:094 0:014)% deficit region toward Virgo. Interpretations of this anisotropy are discussed.

• THE LARGE-SCALE COSMIC-RAY ANISOTROPY AS OBSERVED WITH MILAGRO (2008, background): “…Super-Kamiokande-I, with a median energy of 10 TeV, have identified two coincident regions of interest in their sidereal observations: an excess located at ∼ 75◦ r.a. or “tailin” anisotropy, and a deficit at ∼ 200◦ r.a. or “loss-cone” anisotropy (Amenomori et al. 2006; Guillian et al. 2007).”
• OBSERVATION OF ANISOTROPY IN THE GALACTIC COSMIC-RAY ARRIVAL DIRECTIONS AT 400 TeV WITH ICECUBE (2011, background): “…underground and surface array experiments in the Northern hemisphere have shown that a sidereal anisotropy is present in the TeV energy range (Tibet Air Shower gamma (ASγ) array (Amenomori et al. 2006), SuperKamiokande (Guillian et al. 2007), Milagro (Abdo et al. 2009), and ARGO-YBJ (Zhang 2009)).”
