Abstract
We report on a 50-ks observation of the bright Seyfert 1 galaxy MCG-6- 30-15 with the Rossi X-ray Timing Explorer. The data clearly show the broad fluorescent iron line (equivalent width similar to 250 eV) and t he Compton reflection continuum at higher energies. A comparison of th e iron line and the reflection continuum has enabled us to constrain t he reflective fraction and the elemental abundances in the accretion d isc. Temporal studies provide evidence that spectral variability is a result of changes in both the amount of reflection seen and the proper ties of the primary X-ray source itself.
