Abstract	We propose to observe with XMM-Newton the newly discovered fast rotating B-typestar with rigidly rotating magnetosphere, HD 345439. This enigmatic star is aclose spectroscopic analog of sigma Ori E. The latter has prominent X-rayproperties, it is X-ray bright, hard, and is suspected to display X-ray flares.However, only a few members of sigma Ori E class are known, and it is importantto establish whether the X-ray properties of these stars are similar. With only10 ks exposure time we will achieve the first X-ray characterization of HD345439 and establish its X-ray luminosity and spectral hardness.

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.
