Abstract	Just two days after the 15th anniversary of the classical nova V723Cas, a 55-ksobservation was obtained with XMM in order to study spectral variations throughone full orbit. Unfortunately, the last 8ks of the proposed 63ks fell prey toflare activity, and we lost the most r^ant phase range 0.9-1.1. These dataindicate that the X-ray light curve may follow the same orbital cycle as the OMlight curve, but for secure conclusions, the phase minimum needs to be coveredand a second cycle is needed. Preliminary analysis of the data show intriguingfeatures in the RGS (e.g., blue-shifted absorption lines) and some weak hardemission in the EPIC. A second full orbit (59.9ks) covered in X-rays yieldsdeeper spectra and more light curve coverage for timing analyses.

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.
