Abstract	The CCO pulsar 1E1207.4-5209 is an extremely stable rotator, with a weak B-fieldand a small spin-down rate that has remained constant to <1% over 14.5 years. Itis a unique NS whose B-field is measured as virgul9.e10 G, both spectroscopically andthrough timing. Yet the properties of CCO pulsars cannot be explained unlessthey have strong crustal magnetic fields, perhaps buried by SN fall-backmaterial. We propose a modest program that will continue precise timing andspectroscopy of 1E1207.4-5209 to monitor for a change in B-field that maydiffuse through or break the crust. These observations will also be verysensitive to torque noise due to minute levels of accretion from a hypotheticalfall-back disk.

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.
