Abstract In the ROSAT Bright Survey (RBS) we have almost completely (>99\)identified the more than 2000 brightest high-galactic latitude sources from the ROSAT All-Sky Survey Bright Source Catalogue (1RXS). A smallnumber of sources has empty X-ray error boxes on POSS plates. ROSAT HRIfollow-up observations of RBS1223, a soft object with extreme X-ray to optical flux ratio, confirm a relatively bright X-ray source. Optical imaging down to 26 mag at Keck II reveals no optical counterpart. Chances are high that this is a new isolated neutron star (INS). We propose a 30 ksec observation with XMM in order to i) obtain a high-quality X-ray spectrum of the source and ii) search for possible periodicities.

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.
