| Abstract | Between 2007 and 2020, our XMM-Newton monitoring of SN1987A yielded EPIC and RGSspectra of unprecedented quality. The fluxes and broadening of the numerousemission lines provide information on the evolution of the X-ray emitting plasmaand its dynamics. The soft X-ray light curve has displayed a steady flux declinefrom 2014 decreasing18% of its peak value by 2020. To further monitor theevolution of the X-ray flux and to follow the expected turnover we propose tocontinue our monitoring.This will allow us to further study the time evolutionof the shock conditions and abundance profiles. At high energies EPIC-pn canmonitor the hard band continuum and help to clarify the extremely low observedFe abundance by following the evolution of the detected Fe-K line |

| 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. |
