| ABSTRACT: |
First 2-dimensional sky map of primary cosmic ray flux are obtained
from 5 years of Super-Kamiokande muon data.
About 0.1% of excess and deficit are found in the direction of
Taurus and Virgo, respectively.
Interpretations of this anisotropy are discussed.
The contents of the talk is based on G.Guillian et al., submitted to PRD, astro-ph/0508468.
The talk was origianlly presented in "Les Rencontres de physique
de la vallee d'Aoste (La Thuile 2006)" on March 5-11, 2006.
It was the first presentation of this topic in conferences
from Super-Kamiokande speakers.
Since the time of the original talk in La Thuile 2006 was 25min+5min,
the time in this physics seminor will become rather shorter than regular seminors.
