Abstract	Mrk 493 is bright narrow-line Seyfert 1 galaxy that has been spared of scrutinywith XMM-Newton. A systematic search for strong Fe La emitters in the XMM-Newtonarchive revealed Mrk 493 as a strong Fe La emitting candidate. Investigation ofa short 2003 observation showed the object to be rather impressive exhibiting astrong soft-excess and broad Fe K feature, rapid variability and an apparentlyreflection dominated spectrum. The object appears very similar to 1H~0707-495,but is, on average, twice as bright. Given the combination of characteristicsand source brightness, Mrk 493 demands consideration for detailed study andpotential reverberations mapping. We propose the NLS1 for 190 ks to completesuch work.

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.
