We propose non-disruptive ToO observations of two optically bright Galacticnovae in outburst to observe their temporal UV evolution using the HST/STISechelle. One ToO will target a Carbon-Oxygen type nova and the other ToO will bereserved for the next high energy gamma-ray detected nova. The Fermi/LATdetection of high energy gamma-rays is a recent and unexpected discovery whosemechanism in classical novae is not currently understood. In both cases, UVspectroscopy is essential for determining elemental abundances, mass, dynamics,and structure. Each nova target would also be observed with a single, highresolution XMM/RGS exposure obtained while X-ray luminous (as determined by ourSwift X-ray monitoring).

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.
