Models of the Local Hot Bubble (LHB) assume a uniform temperature and density.ROSAT, and limited XMM, and Suzaku observations suggest this is not the case,but the source of the non-uniformity is unknown. We have shown that one can useXMM spectra to isolate the emission due to the LHB without using a nearbyabsorbing cloud. We propose to measure the non-uniformity of the LHB, thusproviding insights into the nature and origin of the LHB, the issue of SolarWind Charge Exchange (SWCX) contribution to the LHB emission, and the nature ofthe diffuse emission external to the LHB.

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.
