Gamma-Ray Burst (GRB) 130427A is an outstanding event, having the highestgamma-ray fluence of any GRB detected in almost 30 years. Its X-ray and opticalafterglows are extraordinarily bright as well, and this event has potential tobe the longest observable GRB since the launch of Swift. We propose to observethis exceptional GRB with XMM-Newton virgul2 years after the trigger, to determinethe late behaviour of its X-ray afterglow. It represents an unique opportunityto detect and study an X-ray afterglow at such late times. Determining thespectral and temporal indices of the X- ray emission will give us a better gripon the environment and test explosion models. The proposed observations are anextension of those already performed on this burst by the PI with XMM-Newton.

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.
