Abstract We propose to observe for 150 ks the bright Seyfert 1 galaxy Mrk 279 with XMM,using RGS as the principal instrument. The spectrum of Mrk 279 displaysabsorption by ionized gas and a variety of emission lines. In particular, broademission structures are seen around OVIII Ly alpha and OVII triplet. They can beinterpreted as emission from the Broad Line Region (BLR). Only with the largeeffective area of RGS we can put constraints on the ionization and velocitybroadening of such lines, to convincingly test if these features arise from theBLR as defined from optical and UV broad lines.

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.
