Moon shadow analyses are standard methods to calibrate cosmic-ray detectors.
We report on a three-year observation of cosmic-ray Moon and Sun shadows in
different detector configurations. The cosmic-ray Moon shadow was observed
with high statistical significance (> 6σ) in previous analyses when the
IceCube detector operated in a smaller configuration before it was completed
in December 2010. This work shows first analyses of the cosmic-ray Sun shadow
in IceCube. A binned analysis in one-dimension is used to measure the Moon
and Sun shadow with high statistical significance greater than 12σ.
