Abstract	We request two new XMM-Newton observations of the X-ray bright Compton-thin Sy 2NGC 526a, each 40 ksec in duration, with one in each visibility window duringAO12. We will compare the newly-obtained spectra with archival spectra for thisobject obtained with XMM-Newton and other missions; this will allow us toquantify the variability in the parameters of the partial- and full-coveringneutral components over timescales of both years and months. The results willyield observational constraints for new, clumpy-absorber models.

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.
