Supergiant shells with diameters approaching 1000 pc may break through thegaseous disk of their host galaxy, and transfer energy and mass into thegalactic halo. The Large Magellanic Cloud contains several supergiant shells,among which LMC2 has the most spectacular filamentary shell structure and thebrightest diffuse X-ray emission. The X-ray emission exists within the opticalshell boundary and extends beyond the southern shell rim. We propose to use theXMM-Newton EPIC cameras to map LMC2 and its southern extension in order to studythe physical structure of LMC2 and the role it plays in the global structure ofthe interstellar medium. This program was awarded time in AO1, but virgul60% of theobservations were corrupted by high background. We request make-up time to complete our program.

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.
