Description We propose to monitor the optical to X-ray spectrum of the NLSy1 Mkn478 with XMM. Our main scientific goal is the investigation of the nature of the optical to X-ray Spectral Energy Distribution and of its variability in relation with the changes of the X-ray nuclear continuum. The measure (or the lack) of lags between the radiation emitted in different energy bands will be used to study the casual relations among the physical processes occurring in the nuclear environment. Time delays between the hard X-rays and any narrow-band reprocessing features will strongly constraint the geometry of the reprocessing matter. The required 150 ks of total exposure time are arranged in an observing

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
