Black hole binaries show high frequency QPOs, the timescales of which impliesthey must be produced close to the event horizon. Our discovery of the firstsignificant AGN QPO gives a unique opportunity to study these in greater detailthan is possible in BHBs. A single re-observation of the QPO would show that itis a characteristic feature of this source, but the QPO is transient, notpresent in the short followup observations. We propose virgul10 snapshots of 30 kseach (the maximum possible visibility in this AO and for the remaining lifetimeof XMM-Newton) to re-detect the QPO and study its properties. This longerobservation will allow a great deal of secondary science to be achieved fromthis important AGN for variability studies including determining the origin of the sources enormous soft excess.

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.
