  The IceCube Observatory has collected over 577 billion cosmic-ray induced
muon events in its final configuration from May 2011 to May 2020. We used this
data set to provide an unprecedented statistically accurate map of the cosmic
ray arrival direction distribution in the TeV-PeV energy range scale in the
Southern Hemisphere. Such an increase in event statistics makes it possible to
extend the sensitivity to anisotropies at higher cosmic ray energies and
smaller angular scales. It will also facilitate a more detailed assessment of
the observatory stability over both short- and long-time scales. This will
enable us to study the time variability of the cosmic ray anisotropy on a
yearly-base and over the entire data sample period covering most of the solar
cycle 24. We present the preliminary results from the study with the extended
event sample.
