We propose to obtain a well-exposed X-ray spectrum of the X-ray transientNarrow-Line Seyfert 1 galaxy (NLS1)/transient Broad Absorption-line AGN WPVS 007with XMM-Newton simultaneously with our approved HST/Chandra observations. Thegoal is to establish a tight connection between the UV broad absorption linetroughs found in FUSE observations and the strong partial covering absorberfeature found by Swift. WPVSvirgul007 showed a dramatic transformation into a BAL-QSObetween a 1996 HST observation and a 2003 FUSE observation; the recent SwiftX-ray detections suggest that the absorber has started to disappear. Thereforeit is crucial for our HST COS UV spectroscopy to know what the status of theX-ray absorber is.

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.
