Scientific paper

Black hole binaries show high frequency QPOs, the timescales of which implies they must be produced close to the event horizon. Our discovery of the first significant AGN QPO gives a unique opportunity to study these in greater detail than is possible in BHBs. A single re-observation of the QPO would show that it is a characteristic feature of this source, but the QPO is transient, not present in the short followup observations. We propose ~10 snapshots of 30 ks each (the maximum possible visibility in this AO and for the remaining lifetime of XMM-Newton) to re-detect the QPO and study its properties. This longer observation will allow a great deal of secondary science to be achieved from this important AGN for variability studies including determining the origin of the sources enormous soft excess.
