RBS 1423 is one of only a few high-luminosity QSO with a relativisticallybroadened Fe K line, which was found by Krumpe et al. (2007) from a 20 ks XMMobservation. The QSO is an important case study for probing the inner accretiondisk and strong gravity regime in high-luminosity QSO, and potentially theblack-hole spin. We propose another XMM 20 ks snapshot to investigate if the FeK line is persistent or variable. This will help to strategize future longerfollow-ups since a varaiable line would benefit from a monitoring program,whereas a deep exposure to better constrain the accretion disk and black-holespin would be more appropriate for a persistent line.

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.
