We request weekly monitoring of a new classical nova over the first two monthsof the outburst, with the goal of obtaining the most detailed X-ray observationsto date of this phase of the outburst evolution. These new observations willallow us to constrain the onset time of the early X-ray emission and to trackany changes in this emission as the outburst evolves. We will investigate theorigin of these X-rays (internal shocks or interaction with an external medium)through spectral modeling, and comparison with complementary radio and opticalobservations. Understanding the physics of mass loss from novae, both inoutburst and during the accreting phase, is crucial for determining the longterm evolution of the white dwarfs in these systems.

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.
