Abstract	We request 50 ksec of XMM time to obtain EPIC spectra of two early B type stars,HD66665 and HD63425, which have observable properties similar to tau Sco.Specifically, they are both slowly rotating, magnetic early, main sequence Bstars with peculiar UV resonance line profiles. The proposed observations willdetermine whether their X-ray spectra also contain an anomalously hard componentlike tau Scos. If so, the new observations will provide valuable insight intothe interaction of X-ray and UV spectral characteristics and will demonstratethat tau Sco is not a simple curiosity, but rather the proto-type of a class ofmagnetic stars which are, perhaps, part of a sequence, or a particularevolutionary phase of massive, magnetic stars.

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.
