Scientific paper

PHL 1092 is known for its extreme X-ray variability observed by previous X-ray missions (see results from the ROSAT monitoring of the source by Brandt et al 1999). The fast and large amplitude variability is common in narrow-line type objects but rather unusual given the quasar-type luminosity of the source (about 10^{45} erg/s in the 0.4-10 keV rest-frame). The flux variability is also associated with complex spectral variability revealed (but poorly understood) from previous relatively short XMM-Newton observations. We propose to observe PHL 1092 with XMM-Newton to investigate in great detail the nature of the spectral complexity and of the extreme X-ray
