We propose to observe the Seyfert 1 galaxy Ton 1388 for 130 ks. This sourceshows 16 Lyalpha absorbers with a redshift between 0.01639 and 0.17366 along theline of sight. A Chandra LETGS observation showed evidence for the X-raydetection of three of these Lyalpha absorbers. With the proposed observation wewill confirm these three detections, and place tight upper limits to the columndensities of the remaining 13 Lyalpha absorbers. The RGS spectra will allow usto characterize the Warm-Hot Intergalactic Medium along the line of sight,obtaining total column densities, the dominant ionization process: collisionalor photionization, and CNO abundances.

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.
