Abstract	Iron K relativistic reverberation has been observed in several AGN, with delayscomparable to the light crossing time very close to the black hole. In thisframework, objects with no reflection or with reflection only spectra shouldshow no relativistic reverberation. An object with no reflection was the targetof a previous accepted XMM proposal. This proposal explores the case of areflection- only source. We request a 120 ks observation of thereflection-dominated MRK 478, a highly variable object whosereflection-dominated state is brighter than other objects in similar state. Thegoal is to directly test the prediction of relativistic reverberation that nodirect-to-reflected delay is present. The data will allows us to search for second order delays in the reflected emission itself.

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.
