Abstract	JWST promises transmission spectroscopy of the atmospheres of nearby exoplanets,opening a new window on exoplanet characterization. The remarkable threesuper-Earths covering the rocky to gaseous range recently discovered orbiting GJ9827 makes it the closest exoplanet host discovered by Kepler to date and a topfive JWST target. The X-ray and EUV emission of stars is vital for understandingthe atmospheres and evolution of their planets. However, GJ 9827 has not yetbeen detected at X-ray or EUV wavelengths, and its high-energy activity can onlybe extrapolated from other indices. We propose three XMM-Newton snapshots of GJ9827 in order to characterize the coronal activity that will be vital forinterpreting its planets atmospheric signatures.

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.
