  We study the timing and spectral properties of the intermediate polar MU
  Camelopardalis (1RXS J062518.2+733433) to determine the accretion modes and
the accretion geometry from multi-wavelength, multi-epoch observational data.
Light curves in different observed energy ranges (optical, UV, X-ray) are
extracted. The timescales of variability in these light curves are determined
using Analysis of Variance. Phase-resolved X-ray spectra are created with
respect to the most prominent detected periodicities and each fitted with an
identical model, to quantify the differences in the fitted components. The
published tentative value for the spin period is unambiguously identified with
the rotation period of the white dwarf. We detect a distinct soft X-ray
component that can be reproduced well by a black body. The analysis of data
obtained at different epochs demonstrates that the system is changing its
accretion geometry from disk-dominated to a combination of disk- plus
stream-dominated, accompanied with a significant change in brightness at
optical wavelengths.
