GT- G272.2-3.2 is a shell-type SNR of virgul15. diameter discovered in the ROSATall-sky survey. It has been confirmed by measurements of non-thermal radioemission at 1.4, 2.4, 4.8 GHz. The X-ray spectrum is rather hard with anapparent temperature of 14 Mill. K. Distance estimates run from 1 to 2.8 kpc,which we want to constrain further as well as the age by measurements with XMM.The high temperature is conspicuous and might mimic a power-law type spectrum,which, if confirmed, would put G272.2-3.2 in the same class of X-ray non-thermalshell type SNRs as SN 1006, RX J0852.0-4622, etc.

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.
