Abstract	The stellar winds of B supergiants (SGs) go through a discontinuous jump intheir terminal velocities and mass loss rates at spectral type B1 which isreferred to as the bistability of B SGs. Since wind shocks produce the X-rayemission and are highly dependent on the stellar wind parameters, B SGs providea natural laboratory to study the relationship between the radiative force,stellar wind, and X-ray emission. We are requesting EPIC-pn observations of 4known B SG X-ray sources located at or near the bistability jump. The X-rayfluxes show a decrease, but the cause is not known. Spectral analyses of theseEPIC observations will allow us to test the predictions of the stellar windshock model.

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.
