| Abstract | We propose a monitoring program of the recently erupted FU Ori type variablesHBC~722 and 2MASS J06593158-0405277. We have found intriguing order-of-magnitudechanges in X-ray luminosity and photoelectric absorption in early outburst. Wepropose to start a long-term monitoring program aimed at determining how theX-ray emission and absorption components of these two FUors evolve with time. |

| 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. |
