|Title||Sampling the solar sind at solar maximum in 3D with comets|
|Author||Dr Konrad Dennerl|
|Description||We propose to utilize comets as natural space probes for sampling the heavy ion content of the solar wind at solar maximum in 3D, by investigating the X-ray emission which results from charge exchange interactions between solar wind ions and cometary neutrals. The solar maximum is particularly well suited for such studies. During AO-12, which coincides with solar maximum, 4 comets will be favorably placed for XMM-Newton: C-2011 L4 (PANSTARRS), 2P-Encke, C-2012 S1 (ISON), and 154P-Brewington, sampling the solar wind between 10 deg and 75 deg heliographic latitude. This proposal makes full use of the spectral, temporal, and spatial resolution of XMM-Newton, of its full field of view, and of all its six (PN, MOS1, MOS2, RGS1, RGS2, OM) scientific instruments.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
