Abstract	Dramatic optical/IR outbursts from PMS stars, which signal the onset of rapidmass-infall onto such stars through their accretion disks, cannot be predicted.However, our Chandra and XMM monitoring of the outburst of V1647 Oridemonstrates that an high accretion rate can also produce an X-ray outburst,and, indeed, that X-ray monitoring of PMS accretion bursts represents a newobservational window on the magnetic interaction between the stellarmagnetosphere and the accretion disk. We have been allocated Chandra ToO time tomonitor with snapshots, beginning just after discovery, any such outburstsduring Cycle 9. We propose an 120 ks-exposure XMM ToO of any X-ray outburstconfirmed with Chandra to perform X-ray spectroscopy and to investigate X-ray variability on a timescale of a day.

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.
