Abstract	0056-363 was observed twice with XMM- Newton , in 2000 and 2003. In the secondobservation, the soft X-ray emission was less prominent, the UV flux lower, thehard X-ray emission flatter, and the iron line much less intense than in thefirst observation. These changes are consistent with a scenario in which theinner disc radius changed between the two observations, being close to theinnermost stable orbit in the first observation, while the disc was truncated ata larger radius in the second observation. We propose to observe Q0056-363again, twice (once per visibility window), for 40 ks each, to confirm or ruleout the changing inner radius. scenario, and to further study the ratherextreme spectral evolution of this source.

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.
