Description A broad, intense and skewed iron K alpha fluorescent emission line was detected in the April 19, 1998 {it BeppoSAX} observation of the {it microquasar} GRS 1915+105, in a state of less pronounced variability, providing for the first time evidence for relativistic disc line emission in this source. The limited sensitivity and energy resolution of {it BeppoSAX} did not allow, however, to measure the disc parameters with the desired precision. We request a 25 ks XMM-- Newton TOO observation, triggered by the occurrence of a similar ..plateau. state, to measure the disc parameters and estimate the Black Hole spin.

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.
