Abstract	We propose a monitoring program of ESO 362-G18, a X-ray bright local Seyfert 1.5which exhibits significant variation of the properties of the X-ray absorber onrelatively short timescales. We identify a likely variability timescale of 1week, and we propose to monitor the source for 2 weeks and explore all shortertimescales by making use of Chandra and XMM-Newton unique capabilities. Werequest a total of 5x10 ks time-constrained observations with Chandra and 1x75ks unconstrained observation with XMM-Newton.

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.
