Abstract We propose monitoring observations of supersoft X-ray sources. The classicalnova V4743 Sgr, for which the best spectra of a luminous supersoft X-ray sourcehave ever been obtained, should be monitored once again during the coming year,also in order to measure the length of hydrogen burning. We then propose that RXJ0533.7-7034, a transient source observed for a few months in the LMC and neverfound to be luminous again, should be observed in five short snapshot exposures(every two and a half months) so that we may determine whether it underwent ahydrogen shell flash, and what its recurrence time scale may be.

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.
