GT-we propose two high-priority observations of the superluminal sourceGROJ1655-40 and a low-priority observation of GRS 1716-249. GRO J1655-40 is theclosest of jet X-ray transients showing repeated outbursts and quiescentepisodes lasting weeks/months. The high quality X_ray spectra to be obtainedwith EPIC will provide crucial information on accretion and relativisticejection processes of these sources.

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.
