We propose to observe a set of 5 bright Fermi-LAT sources located athigh-Galactic latitude, with a high significance detection but without anyidentified counterparts to date. For those sources, the moderately largeposition uncertainties make counterpart discovery more challenging. Our proposedobservations are for 20 ks per source, covering the LAT error region in a singlepointing. We will determine the X-ray position, flux, temporal and spectralproperties for any sources detected by XMM within this region. These resultswill be used by radio, near-IR, and optical telescopes, whose smaller fields ofview require more precise localization for follow-up, to determine clearcounterparts for these gamma-ray sources.

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.
