Blazars are AGN with powerful relativistic jets. While their high energyemission processes are still poorly understood, upcoming X-ray polarizationobservations can shed much needed light. ISP blazars are particularlyinteresting since their X-ray emission falls in the transition region betweensynchrotron and Inverse-Compton (IC) providing ideal laboratories to testemission scenarios. Here we propose an {\it XMM} observation of one of the bestISP candidates aiming to quantify its synchrotron and IC contributions throughthe 1-10 keV band. The proposed observations will allow for a detailedprediction of the X-ray polarization and a deeper understanding of the blazarSED.

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.
