| Description | We propose a 30 ks XMM observation of the X-ray transient XTE J0421+56 (CI Cam) in quiescence. During part of a 10 day outburst in 1998 April, this source exhibited a relativistic radio jet and moving X-ray emission lines. Green Bank monitoring indicates that CI Cam continues to be a radio source. XTE J0421+566 was clearly detected in quiescence by BeppoSAX in a 45 ks observation, some 150 days after the outburst. The count rate was too low to obtain a useful spectrum. The proposed XMM observation will provide this, and allow a sensitive search for the intense oxygen feature seen during the latter part of the outburst by BeppoSAX. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
