Abstract Since an MOS1 instrument anomaly (possible meteorite impact) in rev. 961, MOS1 CCD6 is inactive. We propose to check whether a pinhole can be identifiedin the MOS1 medium filter (e.g. due to micrometeorites), inside the filter areawhich, in nominal position, is located above the now inactive CCD6 (ref.as F-6area). Therefore this F-6 area must be moved above active CCDs by moving thefilter wheel out of the nominal position. The filter wheel position must bechanged two times, first by 12 degrees, second by 8 degrees, into the directionof the thin2 filter, to place the largest possible fraction of the F-6 areaabove active CCDs. For each position a set of 5 FF RPP mode diagnostic exposuresmust be be taken from three CCDs (1,2,7).

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.
