We propose two 20 ksec XMM-Newton observations of the X-ray bright gamma-rayblazar 3Cvirgul279 simultaneous with GLAST/LAT. The main goal is to measure its X-rayproperties (spectrum, variability) in order to (1) improve our knowledge on theX-ray emission of the blazar, and (2) to supplement and correlate them tosimultaneous GLAST/LAT Gamma-ray observations (30 MeV-300 GeV). SimultaneousGLAST observations of 3C 279 are guaranteed (assuming proper operation then).The high-energy data will be supplemented by ground-based measurements, addingfinally up to multifrequency spectra which have unprecedented accuracy and willextend up to high-energy gamma-rays. Such high-quality SEDs will provide severeconstraints on their modeling and have the potential to discriminate among models.

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.
