| Abstract | We ask for 4 TOO observations of 50 ks each to observe 4 blazars, conditional tostringent and well defined triggering criteria based on 1) hard or soft X-raybrightening; or 2) TeV brightening; or GeV brightening or 3) opticalbrightening. With the XMM-Newton observations of blazars in flaring state wewill investigate their X-ray spectra evolution over a timescale from minutes tohours. This will provide r^ant information on the radiation mechanisms inextragalactic relativistic jets. XMM-Newton TOO prompted by Swift/BAT orINTEGRAL or GLAST or TeV telescope would provide for the first time X-rayobservations of flaring blazars activated by very high energy triggers. We willcoordinate these observations with a similar Integral program already active. |

| 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. |
