We request a 126ks .stare. of 3C279 to combine with our 15yr RXTE light curve inorder to measure the power spectral density (PSD) of the X-ray flux variationsover timescales from virgul1E4 to 1E8 s. The data will determine whether the PSD hasa break at virgul5E-7 Hz from a slope of -1 at low variational frequencies to virgul -2.4at high frequencies. This is expected if, like the radio galaxies 3C111 and3C120, the blazar follows the break timescale-mass-accretion rate scalingrelationship found for non-beamed Seyfert galaxies and X-ray binaries. Since theX-rays observed in 3C279 arise from the highly relativistic jet, a positiveresult will demonstrate that even the fastest jets are driven from the accretiondisk/corona rather than from the ergosphere of the black hole.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
