This proposal is a request for the reobservation of an AO-3 target for which a25 ks exposure was almost entirely contaminated by strong soft proton flares,and thus cannot be used to meet our scientific objectives. This exposure is thelinch-pin to the analysis of the other observations in this program; without thereobservation, the interpretation of the other observations will be equivocal.We will be measuring the temperature of soft components of the Galactic X-raybulge as close to the nucleus as possible, through Baade.s Window. We will thenmeasure the change in temperature with distance from the nucleus. From thesemeasures we expect to determine the thermal history of the gas in the X-rayemitting bulge and thus the impact of the central engine.

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.
