Observations of the bright Seyfert 1 galaxy MCG-6-30-15 with the Rossi X-ray Timing Explorer clearly show evidence for the broad fluorescent iron line, and the Compton reflection continuum at higher energies. A comparison of the iron line and the reflection continuum has enabled us to begin placing constraints on the reflective fraction versus elemental abundance relationship in the accretion disk. Temporal studies with our 50ks RXTE observation provide evidence that spectral variability may be due to both intrinsic changes in the source itself as well as the amount of reprocessing. ASCA observations have shown strong evidence for a variable iron K emission line; our recent 400ks joint ASCA + RXTE observations will allow for study of the variability of the reflection continuum in detail for the first time.
