Her X-1 is an unusual accretion-powered pulsar system exhibiting a great wealth of phenomena. This eclipsing system contains a 1.24 second period pulsar in a 1.7 day circular orbit with its optical companion HZ Her. In addition, the system displays a longer 35-day cycle. This cycle has Main High and Short High states, lasting about ten and ve days respectively, which are separated by ten day long Low states. Here the changes in X-ray spectrum observed with the GINGA satellite are studied as a function of the 35-day cycle. The spectral changes are discussed in terms of physical causes, such as the e ects of the precessing accretion disk in Her X-1.
