Abstract	We propose to obtain XMM-Newton observations of three spectroscopically singlesuperflare stars with large rotation periods (Prot >10 d) to test whether theircoronae adhere to the rotation--activity paradigm. While the strongest flaresobserved on the Sun release about 1e32 erg, Kepler observed a rare species ofG-type dwarfs that produce white-light flares releasing up to four orders ofmagnitude more energy. Notwithstanding their enormous optical outbursts, weidentified two single superflare stars, whose coronae seem to adhere to theconventional rotation--activity relation. Combining the available information,we identified the best single superflare stars to enlarge the sample of ourX-ray study.

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.
