Description We propose to use XMM to pin down the classification of the as yet undefined source GT 2318+620 as a Galactic or an extragalactic object. This target has been suggested to be a Radio-Jet X-Ray Binary, based on radio observations and its possible association with one Uhuru X-ray source. Our optical studies of the source revealed a red, almost featureless spectrum and faint extended emission around a point-like core, more characteristic of BL Lacertae objects. Using XMM we wish to obtain the first reliable X-ray detection of GT 2318+620 and determine the true nature of this peculiar source by a careful examination of its X-ray spectrum and variability characteristics. XMM observations will be complemented by simultaneous ground-based optical, near-IR and radio studies.

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.
