Abstract	We propose a 32 ks EPIC ToO to observe any new optical/IR outburst from a PMSstar. The proposed observations will yield the contributions of soft X-rayemission due to shocks in accretion streams or jets versus harder X-rays fromstar-disk magnetic reconnection activity during the eruption, as well as thedegree of X-ray variability on a timescale of hours. These results will becompared with those obtained for the recent outbursts of, e.g., V1647 Ori and EXLup, so as to begin to establish the dependence of the X-ray characteristics ofPMS star eruptions on, e.g., PMS accretion rate and evolutionary state.

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.
