Abstract
Results of two observations (1996 July and 1997 September) of the bina ry pulsar Her X-1 by the Rossi X-Ray Timing Explorer (RXTE) are presen ted. We discuss the energy spectra at energies 3-20 keV as measured by the PCA. The data can be described by the sum of two power laws, one of which is modified by absorption in cold material, plus an Iron emis sion line. In this poster we discuss spectra and color/color diagrams for a pre-eclipse dip observed in 1996 July and we present preliminary results for the 1997 September observation of the 35 day Turn-On.
