| Abstract | LS I +61 303 is a high mass X-ray binary that has been recently detected as avariable TeV source by MAGIC. We propose to conduct, for the first time,simultaneous X-ray and TeV observations, complemented with a radio monitoring,during several consecutive days centered around the orbital phase where themaximum TeV activity takes place. These observations will allow us to followinter-day spectral variability at X-ray and TeV energies. They will provide abetter sampled evolution of the X-ray flux and photon index around the phaseswhere X-ray outbursts are detected. They will also allow to verify the higherflux - harder spectrum correlation and the apparent non-existence of spectrallines. All this will be crucial to constrain physical properties of the emitter. |

| 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. |
